***

When starting Parley under Wayland the window does not update when typing or clicking anything. I have to resize the window or trigger some other action so that a repaint happens.

STEPS TO REPRODUCE
1. Open Parley.
2. Interact in any way the program.

OBSERVED RESULT
Nothing happens visually.

EXPECTED RESULT
The GUI is updated.

SOFTWARE/OS VERSIONS
Windows: -
macOS: -
Linux/KDE Plasma: Gentoo Linux with Plasma 5.27.4
(available in About System)
KDE Plasma Version: 5.27.4
KDE Frameworks Version: 5.104.0
Qt Version: 5.15.8

ADDITIONAL INFORMATION
The problem can be workarounded by starting Parley under X11 or forcing XWayland with `QT_QPA_PLATFORM=xcb parley`.

Comment 1 Andreas Cord-Landwehr 2024-02-18 08:56:29 UTC 
A temporary solution until we find a fix, you can run parley with "-platform xcb" to workaround this problem. The actual problems seems to be quite deep in the render stack and might need some time to fix/cannot be fixed in Parley alone.

Fix window updates on wayland

This refactors all (wrongly) used KXmlGuiWindow objects to be just
QWidgets. This avoids wrong calls to winid() which leads to severe
window render update misses.
