SUMMARY Similar to this on reddit: https://www.reddit.com/r/kde/comments/m6tys4/clipboard_very_inconsistent_on_kde_neon/ But I want to make sure this is here on the list. I'm fairly new here so please tell me where I should put it STEPS TO REPRODUCE 0. Use wayland 1. Select text (somewhere) 2. ctrl + c (copy shortcut) 3. check clipboard (every second or third copy is an empty string or not copying at all) OBSERVED RESULT - copied line is empy (or additional empty one is copied) EXPECTED RESULT - copied selected text SOFTWARE/OS VERSIONS Linux/KDE Plasma: 5.13.11-1 (available in About System) KDE Plasma Version: 5.22.4 KDE Frameworks Version: 5.85.0 Qt Version: 5.12.2 Graphics Platform: Wayland ADDITIONAL INFORMATION - Personal note: This is a major issue for me since wayland has major benefits for me when playing games. Some games don't get proper input under x11 but wayland works like a charm.
I've added it here since the issue is fairly old but critical to the adoption of wayland (imho)
Does this happen when copying from - Plasma - normal windows - XWayland windows ?
I used the KWin Debug console to test which windows use x11 (x11 client windows) X11 Client windows: - Firefox (issue found) - Signal desktop app (issue found) - Jetbrains Rider (issue found) XWayland Observed behavior: - Copies most of the times 1 entry for the line + one empty entry - Copies sometimes only an empty entry ------ Wayland: - Kate (no issues, and also no empty line) - Dolphin (Copying the path the the current dir) (No issues) ------- Conclusion: - There seems to be something strange going on when using KWayland (unfortunately used by a lot of applications)
additionally I've tried firefox without XWayland > export MOZ_ENABLE_WAYLAND=1 > firefox -> no issues
