Description lucas_kde.org 2024-07-13 15:12:35 UTC 
SUMMARY
Within an XWayland application, if I use `Ctrl + C` or some menu command for "copy text", I can paste that only within XWayland. Wayland applications never see that copied value. There I can only ever paste what I copied from a Wayland application.

Conversely, I can always copy in a Wayland application and paste to any XWayland application.

Applications copied from:
- Steam
- Discord
- Obisidan
- 010Editor
- IDA

Applications I expected to paste to/see the value:
- Klipper
- `qdbus6 org.kde.KWin /KWin org.kde.KWin.showDebugConsole`
- Firefox
- Wezterm

STEPS TO REPRODUCE
1. Open an XWayland application
2. Copy some text
3. Focus a Wayland application and paste

OBSERVED RESULT
Cannot copy from XWayland to Wayland

EXPECTED RESULT
Copy and paste should work from any application to any application.

It miiiight be related. Since that fix is going to be available in 6.2, can you please test whether the issue is still reproduce there when 6.2 is released? If it is, can you provide more details? The distro, does it happen randomly, or does it happen consistently, what actions are more likely to trigger the issue, etc
