Qt applications are going to run natively on Gnome Wayland session and won't use XCB plugin by default. The XCB plugin can still be used when set using '''QT_QPA_PLATFORM''' variable or using '''app -platform xcb''' option. Other desktop environments already run Qt applications natively on Wayland. This change also includes new client-side window decorations to match Gnome Adwaita theme. | |||

Qt Wayland By Default On Gnome
Summary
Qt applications are going to run natively on Gnome Wayland session and won't use XCB plugin by default. The XCB plugin can still be used when set using QT_QPA_PLATFORM variable or using app -platform xcb option. Other desktop environments already run Qt applications natively on Wayland. This change also includes new client-side window decorations to match Gnome Adwaita theme.

Detailed Description
Qt Wayland plugin has been available for a long time, but it hasn't been in condition where it could be enabled by default. With Qt 5.12 the state of the Wayland plugin is much better and it's becoming more and more reliable.
Benefit to Fedora
Qt applications running with the wayland plugin run generally faster and smoother on Wayland enabled sessions like Gnome Wayland and better support HiDPI displays (respects desktop scale) .
Scope
- Proposal owners:
- Modify Qt 5 (qt5-qtbase) to not exclude Gnome when deciding whether to use the wayland platform plugin
- Update QGnomePlatform with upcoming upstream release including window decorations
- Other developers:
- Test and watch for regressions.
- Release engineering: #Releng issue number (a check of an impact with Release Engineering is needed)
- List of deliverables: N/A (not a System Wide Change)
