For a redirected window a custom shader can be specified to draw the
redirected texture to screen. This is useful for inheriting effects to
customize the rendering.
Two new int uniforms TextureWidth and TextureHeight are added and set
from DeformEffect when rendering the texture.
Currently, fullscreen geometry restore is computed from maximized
geometry restore. However, the latter is set only when the window is
maximized.
Also, updateGeometryRestoresForFullscreen() can be called when the
window has not been moved. Avoid updating geometry restore if the output
has not been changed.
If the animation reaches the end, desktop grid may render the screen
incorrectly. Make sure that PAINT_SCREEN_BACKGROUND_FIRST and flags as
such are set even if animation has reached the end.
Also, while on this, simplify the paintWindow() method by removing
redundant effect status checks.
effects can specify in their json file "X-KWin-Border-Activate":true
and will be listed in the edge menus.
Don't hardcode desktop grid and overview in the kcms
At the moment, if user switches between virtual desktops using a
gesture, panels will loose blurred background because WindowForceBlurRole
is not set.
This change refactors setup code so the slide effect always forces blur
and background contrast when sliding between virtual desktops using a
gesture or animation.
Possibility to implement realtime screenedges gestures in scripted effects,
implement it in the windowsaperture show desktop effect.
* Expose registerRealtimeScreenEdge to JavaScript, the callback will be
a JS function.
* Add the concept of freezeInTime() in the animation js bindings,
it will either create an animation frozen at a given time or freeze a running animation
that can be restored and ran to completition at any time
* add an edges property only for showdesktop as it's not directly on the effect configuration
If desktop wrapping is disabled and user swipes to left but there's no
desktop to left, the slide effect can get stuck active because there's
no desktopChanged() nor desktopChangingCancelled() signal emitted.
This change makes the VirtualDesktopManager explicitly cancel
interactive desktop switching session if the current desktop has not
changed.
Currently, there's a separate pass to filter out windows not ready for
compositing or windows that must be invisible. That has two issues: we
could merge that pass with the pass that populates stacking_order and
"windows" can detach.
libinput_device_get_user_data() can be used to get the associated Device
object with libinput_device. That way, we won't need to maintain a
private list of all input devices.
If the window filter rejects a window, that window won't be in the
stacking_order and henceforth won't be painted, so finalDrawWindow()
does extra work of checking again if the window is accepted.
Effects may perform cleanup when a deleted window is removed. If that
happens and the SceneWindow is accessed, kwin may crash.
The Scene processes Workspace::deletedRemoved() before effects.
In order to fix dereferencing null pointer, this change makes the Window
destroy its associated SceneWindow.
Format modifiers enable the graphics hardware to be much more efficient,
especially when it comes to multi-gpu transfers. With the issues regarding
bandwidth limits now solved, enable them by default to make all supported
systems benefit from them.
CCBUG: 452397
CCBUG: 452219
When explicit modifiers are used, it can happen that Mesa chooses modifiers that make
the display hardware hit bandwidth limits. In that case, atomic tests fail and the
outputs don't work, or KWin may even crash.
In order to work around that, DrmGpu now removes the used modifier whenever an atomic
test fails, and tries to find a working combination of outputs and modifiers.
If a window is destroyed before the frame is presented, the window
pointer will be dangling.
In order to make kwin handle that case correctly, the window is captured
using a QPointer.
While having all state be public is great for avoiding the boilerplate that
comes with setters and getters, it also exposes more state than necessary
to the rest of the backend and makes it more error-prone if more than one
part of the state needs to be changed at the same time.
WindowThumbnailItem doesn't depend on features that are available only
with managed window.
By making WindowThumbnailItem work with all kinds of windows, its code
is easier to work with and refactor.
Instead of passing all possible field values to the initialize()
function, pass all relevant data in a struct. With designated
initializers, it's more readable and makes code more comprehensible.
The general goal is to split Output's data in two categories - general
information about the output (e.g. edid) and mutable state (position,
mode, etc).
With this, the drm backend will be able to associate drmModeModeInfo
with Output's modes, which can be useful if there are several modes with
the same resolution and refresh rate but different flags.
This makes KWin switch to in-tree copy of KWaylandServer codebase.
KWaylandServer namespace has been left as is. It will be addressed later
by renaming classes in order to fit in the KWin namespace.
Instead of creating a gammaramp object with a fixed size, make the color
device create a color transformation object that can be used to construct
arbitrary LUTs. This is needed in order to support tiled displays well
and is useful for further color management work.
When we do more color management stuff we'll need it in more places,
making it a hard requirement reduces the amount of needed ifdefs and
should make adding color management features a little simpler.
being naturalx something that needs to map to the actual geometry of the window which is in absolute coordinates but mapped to a view which geometry correspond to the one of one particular screen (plus the layout the thumbnail lives in has its own geometry in the scene)
Some Toplevel properties were redefined in the AbstractClient class to
allow property mutability.
Now, since both classes were merged, those properties can be defined
only once.
