| **************************************************************************** |
| |
| - [QTBUG-66784] Added APIs for xdg-shell stable. |
| - xdg-shell unstable v5 is now deprecated. Existing compositors should |
| migrate to unstable v6 or stable. |
| - Features for server buffer integrations have been renamed. |
| "drm-egl-server" is now "wayland-drm-egl-server-buffer" and |
| "libhybris-egl-server" is "wayland-libhybris-egl-server-buffer". |
| - [QTBUG-49809] Added support for wl_subsurface.place_above and |
| place_below in WaylandQuickItem. |
| - QWaylandQuickItem::sendMouseMoveEvent was added to allow sending |
| generated mouse move events from QML. |
| - Added API for installing a socket on which bind() and listen() have |
| already been called into the event dispatch loop. This facilitates |
| socket-activated compositors. |
| - Added a new categorized logging namespace "qt.waylandcompositor" and |
| renamed "qt.compositor.input.methods" to |
| "qt.waylandcompositor.inputmethods". |
| - Fixed a bug where some signals on QWaylandSurface were emitted before |
| all double buffered state had been applied. |
| - [QTBUG-70163] Fixed a bug where destroying a WaylandQuickItem would |
| delete the OpenGL texture for all other WaylandQuickItems using that |
| surface. |
| - Fixed a bug that caused some clients to abort in libwayland when a |
| surface left an output. |
| - Fixed an issue where the WaylandOutput.window QML property had to be set |
| before the WaylandOutput.sizeFollowsWindow property. |
| - Fixed a bug where outputAdded was not emitted if a new output was added |
| through QWaylandCompositor::setDefaultOutput. |
| |
| - xdg-shell v6: |
| * Requests to enter/exit fullscreen mode are now handled. |
| * Minimum and maximum sizes are now respected when resizing. |
| * Fixed an edge case in moving an initially maximized XdgShellV6 surface |
| to windowed mode. |
| * ShellSurfaceItems now re-issue configure requests with updated sizes |
| when the size or available geometry changes on an output used by a |
| maximized or fullscreen surface. |
| |
| - wl-shell: |
| * ShellSurfaceItems now re-issue configure requests with updated sizes |
| when the size or available geometry changes on output used by a |
| maximized or fullscreen surface. |
| |
| **************************************************************************** |
| * QPA plugin * |
| **************************************************************************** |
| |
| - [QTBUG-66783] Added support for xdg-shell stable. |
| - [QTBUG-69746] Added client-side support for the |
| xdg-decoration-unstable-v1 Wayland extension. Qt clients will now let |
| the compositor draw the window decorations if configured through this |
| extension. |
| - [QTBUG-68834] The window decorations have had a redesign, they now use |
| the window background color instead of the blue gradient. |
| - QT_WAYLAND_SHELL_INTEGRATION environment variable now accepts a |
| semicolon-separated list of shell integrations. |
| - [QTBUG-68838] Deprecated the shell integrations for |
| xdg-shell-unstable-v5 and wl-shell. The stable version of xdg-shell |
| should be used instead. |
| - All shell integrations have been moved to plugins. |
| - Window decorations are now automatically disabled for ivi-application. |
| - Added support for xdg-output-unstable-v1 |
| - Font and UI scaling is now based on the screen scale factor rather than |
| the physical DPI. The logical DPI is set to 96 unless overridden by the |
| the environment variable QT_WAYLAND_FORCE_DPI, which may be set to a |
| specific DPI or to "physical" to get the old behavior. |
| - Cursors now follow the device pixel ratio of the current screen. |
| - Cursor themes are now loaded on-demand, leading to significant memory |
| savings in some cases. |
| - Fixed a bug where QSurfaceFormat::renderableType() was ignored when |
| creating an OpenGL context. |
| - Fixed a bug where the arrow cursor would be shown instead of the resize |
| cursor when hovering over the window decoration border. |
| - [QTBUG-70242][QTBUG-68605][QTBUG-67601] Fixed a bug where offscreen |
| surfaces would get surfaceless EGL contexts. |
| |
| - xdg-shell v6: |
| * Fixed a bug where maximized windows would resize to their unmaximized |
| size if the compositor sent an invalid configure event. |
| * Fixed a bug where buffers were sometimes attached and committed before |
| the first configure event, causing protocol errors. |
| * [QTBUG-63417][QTBUG-63748] Implemented support for maximizing, |
| minimizing, and setting fullscreen with xdg-shell unstable v6. |
| * [QTBUG-53702] QWindow::isActive now follows configure events on |
| xdg-shell unstable v6 (like v5). |
