We're setting this env variable because earlier we used it to force kwin to use its special QPA so we need to change that back to something sensible.
However setting it to Wayland breaks apps that ship their own Qt with missing or broken Wayland support.
Set it to be empty instead. Well-behaved Qt apps will use Wayland regardless because of XDG_SESSION_TYPE.
BUG: 450000
When a window leaves the current virtual desktop, we need to schedule a
workspace repaint so the compositor repaints the old region of the
window on the current desktop.
In hindsight, the scene graph must schedule a repaint, but it's not
doable with the current effects api, it will be changed with future
refactoring changes.
BUG: 444172
Otherwise we get the filename to the library and not the KPackage.
The plugin having this set is most likely a leftover, because KPackage plugins
to not need to define a library.
BUG: 449881
QPlatformScreen::virtualSiblings() must return a list of screens on the
virtual desktop, otherwise QToolTip will use
QGuiApplication::primaryScreen() instead of looking up the screen where
the decoration tooltip must be shown using QDesktopWidget::screenNumber().
BUG: 432860
recordFrame requires an openGL context. This is typically done after a
frame is rendered, but when we send a frame after a cursor move this is
not guaranteed.
BUG: 448162
Despite the argument naming, the input for WindowMotionManager::calculate is supposed to be a
delta, not an absolute time. Giving it a delta fixes the PresentWindows in the DesktopGrid.
BUG: 443971
The quads for the left and right window decorations were broken in
3b4d55837. The problem is only visible for window decorations with more
than one color.
Currently, if kwin_wayland crashes at shutdown, the launcher can
potentially spawn it again. This change addresses that issue by making
the wrapper ignore the QProcess::finished() signal.
Mixing of current and next state can create all sorts of undefined
behavior, e.g. windows not moving to the desired location or
experiencing issues when tiling a maximized window.
BUG: 449541
Currently, the Cursors::currentCursorChanged signal is wired to the
updateCursor() function which calls xcb_xfixes_hide_cursor() or
xcb_xfixes_show_cursor() depending if the cursor is hidden. However, the
currentCursorChanged signal can be emitted if the cursor changed, e.g. a
new pixmap attached, or its visibility status changes.
The zoom effect hides the pointer, but when user hovers ui elements, it
will most likely change and result in more than one xcb_xfixes_hide_cursor()
calls.
It appears like xcb_xfixes_hide_cursor() is implemented as a reference
counter, i.e. if xcb_xfixes_hide_cursor() is called two times, then you
must call xcb_xfixes_show_cursor() two times as well.
This change adds a dedicated signal to indicate whether the cursor is
hidden to avoid calling xcb_xfixes_hide_cursor() multiple times while
the screen is scaled.
BUG: 448537
With connection(), we will look up the x11 connection property on
kwinApp() object, which is less efficient than just calling a method on
the app object.
Since the base Platform::applyOutputChanges() implementation only
applies changes to enabled outputs, it's not possible to re-enable a
previously disabled output.
While there's a fullscreen effect, the fall apart effect should avoid
animating windows as it can corrupt or interfere with the active full
screen effect. This matches behavior of many other animation effects in
kwin.
BUG: 449844
QPainter won't let paint with a device pixel ratio less than 1. There
are used to be workarounds to force a device pixel ratio of 1, but they
were removed with fractional scaling corner fix.
This change makes sure that the decoration renderer forces a device
pixel ratio of 1 if the output's scale factor is less than 1 so
calculated texture coordinates match where window borders are rendered
in the texture atlas.
BUG: 449681
They're error prone and don't really work for changing modes. Having
a current mode in DrmConnector also doesn't work well together with
the transactional style of how DrmPipeline operates
AbstractClient::setQuickTileMode() no longer updates electric border
mode, which can leave AbstractClient::electricBorderMode() with an old
value at the next interactive move and potentially result in quick
tiling not work if the user decides to untile and then tile the window
again while still holding left button.
Quick tiling allows you tile a window so it covers one half or a quarter
of the screen. Electric border is basically interactive flavor of quick
tiling, i.e. it allows you to drag a window to the top screen edge to
maximize it.
Currently, it's confusing that tile geometry is computed based on the
electric border mode.
This change converts electricBorderMaximizeGeometry() in a helper that's
used to compute the tile geometry given the desired mode and output
containing the specified QPoint. With that, setQuickTileMode() won't
need to set electric border anymore, which makes tiling code more
comprehensible, but by not a lot unfortunately.
XdgToplevelClient::setFullScreen() won't change the geometry
immediately, so workspace()->updateFocusMousePosition() can be removed.
Also, input handling code takes care of updating the cached mouse
position in the workspace.
If the user wants to move a tiled window, but changes their mind and
tiles the window back to the previous position, the geometryRestore()
will be corrupted because initialMoveResizeGeometry() is the same as the
geometry of the window in the tiled mode.
This change fixes tracking of the geometry restore by precomputing the
geometry restore when starting interactive move. That way, if the window
is untiled and tiled again without release left pointer button, the
geometry restore will be set to the correct value in setQuickTileMode().
This change also adjusts the test suite so such a subtle case won't be
broken again without noticing it.
There was no handling for the drop being cancelled at all, leading to
leaked WlVisit and XtoWlDrag objects. X clients could also be confused
about the state of the drag and for example not being able to start another
drag.
BUG:449362
Flickable by default allows swiping via click-and-drag or
scrolling with the mousewheel, which is weird when the content
is smaller than the available space.
Inhibit this behavior unless there's a need for scrolling.
The present windows effect can crash because a null (0) EffectScreen can
be passed to EffectsHandler::clientArea(), which is a bug.
Use EffectsHandler::virtualScreenGeometry() to get the bounding geometry
of all outputs.
BUG: 449508
The most recently activated window can be an overlay window that covers
all screens. If its center is not at an output with the fullscreen
window, then the fullscreen window's stack position won't be lowered. In
order to fix that, this change makes isActiveFullscreen() use
Toplevel::isOnOutput(), which uses geometry info, to check if both windows
are on the same output.
Since 4881dd63 replaced the double click timer for OffscreenQuickView
with a time check, we need to make sure the timestamp from
XInput/libinput is passed on to the actual QMouseEvent.
BUG: 448477
It can also be applied to client-side decorations. As long as the
compositor can ask the client to use some specific decoration mode, the
"no border" property can be set.
