****************************************************************************
* Qt 5.11.0 Changes *
****************************************************************************
Compositor
----------
- [QTBUG-64600][QTBUG-64604] Added a tech preview for a plugin-based hardware
layer API and a VSP2 implementation (for Renesas R-Car M3 and H3).
- Added QML API for sending touch events to surfaces.
- Information about disconnected/removed WaylandOutputs are now
communicated to the clients.
- Updated the minimal-cpp and minimal-qml examples.
- Added a new example, overview-compositor.
- WaylandQuickItems now get an implicitSize from their wayland surface,
making them behave more like other QQuickItems. Compositors should set
WaylandQuickItem.sizeFollowsSurface to false to get the new behavior.
- Fixed a bug where window state (maximized, active etc.) was reverted if
XdgTopLevelV6.sendConfigure and related functions were called repeatedly
before the client could respond.
- Fixed a bug where keyboard events were not sent to clients in
WaylandQuickItem.keyPressEvent if the surface was not focused through
WaylandQuickItem.takeFocus().
- Fixed a bug where a negative size was requested when resizing on QML
compositors.
- Fixed mouse and touch events being sent to the wrong position for
WaylandQuickItems and ShellSurfaceItems scaled by the compositor.
- [QTBUG-67861] Fixed mouse and touch events being sent to the wrong
position for high DPI surfaces (QML API).
- Fixed crashes when clients tried to use a deleted WaylandOutput or a
Wayland extension.
- Added documentation for XdgShellV6.
QPA plugin
----------
- Clients now automatically change the scale factor when entering a new
screen. I.e. when moving a window from a low-resolution screen to a
high-resolution screen, the DPI will change.
- [QTBUG-54792][QTBUG-64572] Added Support for key composition, accents
and diaereses.
- [QTBUG-59762] When the plugin fails to connect to the Wayland display,
it now fails gracefully so other platform integrations can be tried
instead.
- ivi-shell will now be used automatically if no other shell integrations are
available.
- [QTBUG-62044] Fixed a crash that happened when connecting to a new
screen above or to the left of the other connected screens.
- [QTBUG-63411] Fixed a crash when calling setVisible for EGL windows twice
within one slot.
- [QTBUG-67150] Fixed a crash when a popup was shown without any input
events happening first.
- Fixed a bug where an OpenGL context with a compatibility profile would
be requested even though if it was set to unspecified in
QOpenGLContext::format. This would sometimes cause context creation to
fail.
- [QTBUG-66867] Fixed a crash that sometimes occurred when showing a
window.
- [QTBUG-64696] Fixed a freeze that would sometimes happen on startup on
some compositors.
- Fixed a bug where ABGR2101010 surfaces where submitted as ARGB2101010
surfaces.
- A new logging category has been added for the Wayland platform plugin,
"qt.qpa.wayland".
