Bug ID: 470175
Summary: Without focus, XWayland apps cannot get
Clipboard/Selection change events from Wayland apps.
Classification: Plasma
Product: kwin
Version: 5.27.5
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: shenlebantongy...@gmail.com
Target Milestone: ---
SUMMARY
Since KDE5.27, if an XWayland app doesn't have focus, then the
QClipboard::Changed won't happen if a user copy text from Wayland apps.
Minimum code sample:
https://github.com/SourceReviver/wayland_clipboard_xwayland_bug
STEPS TO REPRODUCE
1. Run the mini code sample above
2. Select or copy text from somewhere else
OBSERVED RESULT
The label from the sample code won't change unless the window got focused
again.
EXPECTED RESULT
The label should change despite having no focus.
ADDITIONAL INFORMATION
* This only happens when copying text from Wayland to the XWayland apps.
* On KDE 5.26, the sample code can detect clipboard changes without focus
* The sample code works OK on GNOME Wayland but not OK on Sway, and I don't
know if this is intended.
* However, I don't find anywhere in the standards about this detail.
