* QWaylandShmBackingStore: Don't clear new buffers in beginPaintKai Uwe Broulik2024-03-051-8/+18
| | | | | | | | | QFile::resize done upon creation of the buffer already ensures the buffer is filled with zeroes, so there is no need to paint it transparent if the buffer had just been created.

* QWaylandShmBackingStore: Split buffer preparation into dedicated methodKai Uwe Broulik2024-02-151-11/+6
| | | | | | | | | | | Drop "resize(QRect)" since it is ambiguous with the resize coming from QPlatformBackingStore. This allows to ensure a back buffer from multiple places, such as the upcoming "scroll" support.

* client: Fix deletion of new queued shm buffers during reconnectDavid Redondo2024-01-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | When reconnecting the cleanup of existing buffers is delayed in order to preserve contents and copy them to buffers belonging to the new connection. Due to the order of events it could happen that a new buffer was deleted along with the old ones but still being referenced by a window. During reconnect all QScreens are removed and new ones added for the wl_outputs on the new connection during the initial roundtrips. When the first new QScreen is added all QWindows move form the placeholder screen to it. This can cause for example QWidgets to repaint. At this point the windows are not reinited yet, and the buffer is queued inside the window. Only afterwards the reconnected signal was emitted which would cause deletion of all existing buffers including the newly queued ones. To fix this the signal is moved after the first roundtrip where all globals are announced and new buffers can be created but no new screens have been announced yet. The signal is renamed to be more fit for its new location. Pick-to: 6.7 Pick-to: 6.6 Change-Id: I06be14d235ac342a4b420176aadad3ccf18178fe Reviewed-by: David Edmundson <davidedmundson@kde.org>
* client: Avoid creating decorations in the render threadDavid Edmundson2024-01-111-1/+0
| | | | | | | | | | | | | | | | | createDecoration is called when on the main thread from when window flags change, implicitly from initWindow, and also every handleWindowStatesChanged which will be called when we get the first configure event in an xdg shell. There is no need to create the decoration in QWaylandGLContext::makeCurrent. Any current call to makeCurrent before the platform window is shown will not create a decoration as there's a check for a shell surface. Any call afterwards will have already been handled by initWindow. Similarly the SHM backend store does not need to handle decorations itself.

* QWaylandShmBackingStore: Preserve buffer contents between framesKai Uwe Broulik2024-01-061-3/+45
| | | | | | | | | | | Doing a memcpy is quite expensive, particularly when only a small region of the buffer (such as a blinking cursor) actually changed. Instead, keep track of the damaged region and paint only what actually changed into the buffer to be used.

* Client: Avoid locking resizing in QWaylandShmBackingStoreVlad Zahorodnii2023-09-111-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QWaylandWindow::setCanResize(false) will block applying configure events. QWaylandWindow::setCanResize(true) will unblock configure events and potentially apply a scheduled configure event if there's one. QWaylandWindow::setCanResize(true) has to be called **after** committing the surface to ensure that the xdg window geometry matches the buffer. We don't want the xdg window geometry change when painting. Unfortunately, setCanResize(true) can be called before the surface is committed when using a RasterSurface, for example - QWaylandShmBackingStore::beginPaint(): calls setCanResize(false) - QWaylandShmBackingStore::endPaint(): calls setCanResize(true) - QWaylandWindow::setCanResize(true): applies pending configure event - QWaylandShmBackingStore::flush(): commits the surface, but the xdg window geometry is wrong now As is, beginPaint() and endPaint() are not entirely correct functions where configure events can be blocked. We need functions that wrap both painting and flushing, which are not feasible with the current backing store design. On the other hand, it's worth noting that blocking configure events in the backing store is not necessary because painting happens on the main thread unlike OpenGL or Vulkan code paths. Given the lack of synchronization points and the fact that rendering happens on the main thread, this change removes blocking configure events in QWaylandShmBackingStore. It fixes dolphin and various other applications that use QtWidgets jumping while being interactively resized.

* Don't floor device scale in `QWaylandShmBuffer::imageInsideMargins`Phan Quang Minh2023-05-291-1/+1
| | | | | | | | | | | | | | | | | The offset of the drawing target returned from QWaylandShmBackingStore::contentSurface() is incorrectly calculated due to `mImage.devicePixelRatio()` being casted to `int` inside `imageInsideMargins`, which causes the scale to be rounded down in case of fractional scaled displays. This causes the window contents to be incorrectly positioned on CSD-requiring compositors (e.g. GNOME), eventually resulting in graphics corruption due to mismatched damage and opaque regions. Fix this by removing the incorrect `int` cast. Pick-to: 6.5 Change-Id: I436d24522d23888b641cb21403f773e8ea113b8d Reviewed-by: David Edmundson <davidedmundson@kde.org>
* Introduce path for surviving compositor restartsDavid Edmundson2023-03-071-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces an optional mechanism for clients to survive a crash and reconnect seemingly seamlessly. In the event of a disconnect from the compositor socket we simply try to reconnect again and replay any data needed so that we maintain a consistent state to where we left off. From an application point-of-view any open popups will be dismissed and we we potentially get a new framecallback, but it will be almost entirely transparent. Users of custom QWaylandClientExtensions will be notified via the activeChanged signal and rebuild as though the compositor had withdrawn and re-announced the global. OpenGL contexts will be marked as invalid, and handled the same way as a GPU reset. On the next frame RHI will notice these are invalid and recreate them, only now against a new wl_display and new EGLDisplay. Users of low level EGL/native objects might be affected, but the alternative at this point is being closed anyway. The entire codepath is only activated via an environment variable.

This does not exclude cases where a loop is prematurely exited just after calling a modifier on the container, as that is safe, if not especially elegant.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old logic didn't care to listen for wl_buffer.release events so it always drew in the same buffer, potentially resulting in tearing if the compositor was scanning out the buffer at the same time. Instead properly cycle between a few buffers and don't reuse the same one until the release event was received. The old code also used to throttle the redraws, unless the buffer was changing, that is unless the window was getting resized. This is now lost, and no throttling is ever done. Doing it properly, by waiting for the frame callback before committing the new buffer shows very noticeable lags with many applications when resizing, because they paint many times per resize event, so they fall behind the cursor. A proper fix will be to implement the support for requestUpdate(), and using it in the applications.

| | | | | | | | | | | | | | | | | | | | Some pointers need to be initialized in QWaylandBuffer and QWaylandShmBuffer, and checked at destruction. This avoids crashes when shm surface creation fails.

* | Namespace the platform pluginsGiulio Camuffo2015-01-291-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | There currently is a QWaylandInputDevice class both in the wayland QPA plugin and in the QtCompositor API. This causes the qwindow-compositor example to crash when running nested in a wayland session due to a mismatch between the two classes. By namespacing all the plugin code we make sure that name clashes will not happen anymore. Change-Id: I17497cff697599200bea68bf01dfde474526390f Reviewed-by: Jørgen Lind <jorgen.lind@theqtcompany.com>

* | Implement high-dpi supportMorten Johan Sorvig2014-12-171-6/+12
|/ | | | | | | | | | | | | | | | | | | | | | | Wayland 1.2 added support for display scaling, where wl_output has a "scale" event informing the the client that the compositor will scale the output surfaces by the given factor. The client then has the option of providing large surfaces to match the target pixel densety and bypass the compositor's scaling. This is done by calling wl_surface::set_buffer_scale. Re-use the current high-dpi support in Qt by implementing devicePixelRatio() for QWaylandScreen and QWaylandWindow. Provide high resolution buffers both for raster and OpenGL graphics. Introduce a new coordinate system: buffer coordinates, which is related to the window coordinate system via an "int scale" scale factor. This scale factor corresponds to Qts qreal devicePixelRatio, but we keep the name and the type in the QtWayland implementation.
