When compositing is turned on, XComposite extension is used to redirect
|
|
|
|
drawing of windows to pixmaps and XDamage extension is used to get informed
|
|
|
|
about damage (changes) to window contents. This code is mostly in composite.cpp .

Compositor::performCompositing() starts one painting pass. Painting is done
|
2007-04-29 17:35:43 +00:00
|
|
|
by painting the screen, which in turn paints every window. Painting can be affected
|
|
|
|
using effects, which are chained. E.g. painting a screen means that actually
|
|
|
|
paintScreen() of the first effect is called, which possibly does modifications
|
|
|
|
and calls next effect's paintScreen() and so on, until Scene::finalPaintScreen()
|
|
|
|
is called.
|

|

2007-04-29 17:35:43 +00:00
|
|
|
There are 3 phases of every paint (not necessarily done together):
|
|
|
|
The pre-paint phase, the paint phase and the post-paint phase.
|
2011-01-30 14:34:42 +00:00
|
|
|
|
2007-04-29 17:35:43 +00:00
|
|
|
The pre-paint phase is used to find out about how the painting will be actually
|
|
|
|
done (i.e. what the effects will do). For example when only a part of the screen
|
|
|
|
needs to be updated and no effect will do any transformation it is possible to use
|
|
|
|
an optimized paint function. How the painting will be done is controlled
|
|
|
|
by the mask argument, see PAINT_WINDOW_* and PAINT_SCREEN_* flags in scene.h .
|
|
|
|
For example an effect that decides to paint a normal windows as translucent
|
|
|
|
will need to modify the mask in its prePaintWindow() to include
|
|
|
|
the PAINT_WINDOW_TRANSLUCENT flag. The paintWindow() function will then get
|
|
|
|
the mask with this flag turned on and will also paint using transparency.
|
2011-01-30 14:34:42 +00:00
|
|
|
|
2007-04-29 17:35:43 +00:00
|
|
|
The paint pass does the actual painting, based on the information collected
|
|
|
|
using the pre-paint pass. After running through the effects' paintScreen()
|
|
|
|
either paintGenericScreen() or optimized paintSimpleScreen() are called.
|
|
|
|
Those call paintWindow() on windows (not necessarily all), possibly using
|
|
|
|
clipping to optimize performance and calling paintWindow() first with only
|
|
|
|
PAINT_WINDOW_OPAQUE to paint the opaque parts and then later
|
|
|
|
with PAINT_WINDOW_TRANSLUCENT to paint the transparent parts. Function
|
|
|
|
paintWindow() again goes through effects' paintWindow() until
|
|
|
|
finalPaintWindow() is called, which calls the window's performPaint() to
|
|
|
|
do the actual painting.
|
2011-01-30 14:34:42 +00:00
|
|
|
|
2007-04-29 17:35:43 +00:00
|
|
|
The post-paint can be used for cleanups and is also used for scheduling
|
|
|
|
repaints during the next painting pass for animations. Effects wanting to
|
|
|
|
repaint certain parts can manually damage them during post-paint and repaint
|
|
|
|
of these parts will be done during the next paint pass.

Use nullptr everywhere
Summary:
Because KWin is a very old project, we use three kinds of null pointer
literals: 0, NULL, and nullptr. Since C++11, it's recommended to use
nullptr keyword.
This change converts all usages of 0 and NULL literal to nullptr. Even
though it breaks git history, we need to do it in order to have consistent
code as well to ease code reviews (it's very tempting for some people to
add unrelated changes to their patches, e.g. converting NULL to nullptr).
Test Plan: Compiles.

Better handling for making the compositing OpenGL context current
With QtQuick2 it's possible that the scene graph rendering context either
lives in an own thread or uses the main GUI thread. In the latter case
it's the same thread as our compositing OpenGL context lives in. This
means our basic assumption that between two rendering passes the context
stays current does not hold.
The code already ensured that before we start a rendering pass the
context is made current, but there are many more possible cases. If we
use OpenGL in areas not triggered by the rendering loop but in response
to other events the context needs to be made current. This includes the
loading and unloading of effects (some effects use OpenGL in the static
effect check, in the ctor and dtor), background loading of texture data,
lazy loading after first usage invoked by shortcut, etc. etc.
To properly handle these cases new methods are added to EffectsHandler
to make the compositing OpenGL context current. These calls delegate down
into the scene. On non-OpenGL scenes they are noop, but on OpenGL they go
into the backend and make the context current. In addition they ensure
that Qt doesn't think that it's QOpenGLContext is current by calling
doneCurrent() on the QOpenGLContext::currentContext(). This unfortunately
causes an additional call to makeCurrent with a null context, but there
is no other way to tell Qt - it doesn't notice when a different context
is made current with low level API calls. In the multi-threaded
architecture this doesn't matter as ::currentContext() returns null.
A short evaluation showed that a transition to QOpenGLContext doesn't
seem feasible. Qt only supports either GLX or EGL while KWin supports
both and when entering the transition phase for Wayland, it would become
extremely tricky if our native platform is X11, but we want a Wayland
EGL context. A future solution might be to have a "KWin-QPA plugin" which
uses either xcb or Wayland and hides everything from Qt.
The API documentation is extended to describe when the effects-framework
ensures that an OpenGL context is current. The effects are changed to
make the context current in cases where it's not guaranteed. This has
been done by looking for creation or deletion of GLTextures and Shaders.
If there are other OpenGL usages outside the rendering loop, ctor/dtor
this needs to be changed, too.

Use nullptr everywhere
Summary:
Because KWin is a very old project, we use three kinds of null pointer
literals: 0, NULL, and nullptr. Since C++11, it's recommended to use
nullptr keyword.
This change converts all usages of 0 and NULL literal to nullptr. Even
though it breaks git history, we need to do it in order to have consistent
code as well to ease code reviews (it's very tempting for some people to
add unrelated changes to their patches, e.g. converting NULL to nullptr).
Test Plan: Compiles.

[x11] Fix visual artifacts during interactive resize
Summary:
When a window is being interactively resized, its contents may jump. The
reason why that happens is because KWin renders partially resized client
window. Composite extension spec says that a window will get a new pixmap
each time it is resized or mapped. This applies to the frame window, but
not to the client window itself. If the client window is resized,
off-screen storage for the frame window won't be reallocated. Therefore,
KWin may render partially resized client window if the client doesn't
attempt to be in sync with our rendering loop. Currently, the only way
to do that is to use extended frame counters, which are not supported by
KWin.
So, in order to fix visual artifacts during interactive resize, we need
somehow forcefully re-allocate off-screen storage for the frame window.
Unfortunately, Composite extension doesn't provide any request to do
that, so the only option we have is to resize the frame window.

Use nullptr everywhere
Summary:
Because KWin is a very old project, we use three kinds of null pointer
literals: 0, NULL, and nullptr. Since C++11, it's recommended to use
nullptr keyword.
This change converts all usages of 0 and NULL literal to nullptr. Even
though it breaks git history, we need to do it in order to have consistent
code as well to ease code reviews (it's very tempting for some people to
add unrelated changes to their patches, e.g. converting NULL to nullptr).
Test Plan: Compiles.

[scene] Fix decoration texture bleeding
Summary:
Quite long time ago, window decorations were painted on real X11 windows.
The nicest thing about that approach is that we get both contents of the
client and the frame window at the same time. However, somewhere around
KDE 4.2 - 4.3 times, decoration rendering architecture had been changed
to what we have now.
I've mentioned the previous decoration rendering design because it didn't
have a problem that the new design has, namely the texture bleeding issue.
In the name of better performance, opengl scene puts all decoration parts
to an atlas. This is totally reasonable, however we must be super cautious
about things such as the GL_LINEAR filter.
The GL_LINEAR filter may need to sample a couple of neighboring texels
in order to produce the final texel value. However, since all decoration
parts now live in a single texture, we have to make sure that we don't
sample texels that belong to another decoration part.
This patch fixes the texture bleeding problem by padding each individual
decoration part in the atlas. There is another solution for this problem
though. We could render a window into an offscreen texture and then map
that texture on the transformed window geometry. This would work well and
we definitely need an offscreen rendering path in the opengl scene,
however it's not feasible at the moment since we need to break the window
quads API. Also, it would be great to have as less as possible stuff going
on between invocation of Scene::Window::performPaint() and getting the
corresponding pixel data on the screen.
There is a good chance that the new padding stuff may make you vomit. If
it does so, I'm all ears for the suggestions how to make the code more
nicer.

Try to invalidate quad cache when shadow is changed
Summary:
213239a0ea0a9c0967bb68d1eda7a8d4d6a09498 tried to address the case when
a wayland client gets shadow after it was mapped, but because of poor
testing from my side, another bug was introduced. If a decoration tooltip
or the user actions popup is shown, then in some cases it can be blank.
Usually, SurfaceInterface::shadowChanged proceeds SurfaceInterface::sizeChanged,
so when the shadow is installed, window quads cache is rebuilt. But
because shell client already knows the geometry of the internal client,
goemetryShapeChanged is not emitted, thus the cache is not updated.
It would be better just to invalidate the cache when the shadow is
installed, uninstalled, or updated. This reduces the number of
unnecessary invocations of Scene::Window::buildQuads and also moves
handling of the window quads cache away from the Shadow class.
BUG: 399490
FIXED-IN: 5.15.0
Test Plan: Decoration tooltips are no longer blank.

Try to invalidate quad cache when shadow is changed
Summary:
213239a0ea0a9c0967bb68d1eda7a8d4d6a09498 tried to address the case when
a wayland client gets shadow after it was mapped, but because of poor
testing from my side, another bug was introduced. If a decoration tooltip
or the user actions popup is shown, then in some cases it can be blank.
Usually, SurfaceInterface::shadowChanged proceeds SurfaceInterface::sizeChanged,
so when the shadow is installed, window quads cache is rebuilt. But
because shell client already knows the geometry of the internal client,
goemetryShapeChanged is not emitted, thus the cache is not updated.
It would be better just to invalidate the cache when the shadow is
installed, uninstalled, or updated. This reduces the number of
unnecessary invocations of Scene::Window::buildQuads and also moves
handling of the window quads cache away from the Shadow class.
BUG: 399490
FIXED-IN: 5.15.0
Test Plan: Decoration tooltips are no longer blank.

[scene] Re-build window quads after creating a WindowPixmap
In order to generate window quads for a window, the scene needs a valid
WindowPixmap tree. If it's time to render the window, the scene will
build window quads for the contents, the server-side window decoration,
the drop-shadow and cache the resulting window quads. With this way of
generating window quads, we need the window pixmap tree to be valid,
or else no contents window quads will be generated.
While the window pixmap tree is guaranteed to be valid at the time of
generation of window quads for Wayland and X11 clients, this is not the
case for Xwayland clients.
When an Xwayland client is created, some time may pass between the
moment it's been created and the moment when a regular wayland surface
has been associated with the xwayland window. If the compositor decides
to render the Xwayland client in that short period of time, the window
quads cache won't have window quads cache.
In order to work around the weird asynchronous behavior of Xwayland
clients, this change makes the scene discard the window quad cache when
a new window pixmap has been created. This will ensure that the current
window quads are always in sync with the current window pixmap tree.
