Bug ID: 478705
Summary: Legacy X11 keyboard support does not receive key mask
state update when Alt+tab is used
Classification: Plasma
Product: kwin
Version: 5.90.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: input
Assignee: kwin-bugs-n...@kde.org
Reporter: wen...@gmail.com
Target Milestone: ---
SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
STEPS TO REPRODUCE
1. Set "All" to X11 legacy app support under kwin wayland
2. start xinput test-xi2 --root
3. first press any key like "a", and see modifier line is "base 0".
4. make sure alt+tab is set for window switching, and the focused window is
wayland window.
5. press alt + tab with alt being held.
6. release all key.
7. press "a" again
OBSERVED RESULT
After that, the any key pressed is with "modifier base 0x8", which means alt
mask is set.
Press alt again will make the state back to normal.
EXPECTED RESULT
modifier is return to "base 0" because alt is released.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 5.90.0
(available in About System)
KDE Plasma Version: 5.90.0
KDE Frameworks Version: 5.246.0
Qt Version: 6.6.1
ADDITIONAL INFORMATION
I suspect that alt is not forwarded to xwayland at all since kwin captured it
for alt+tab, and later xwayland's key state is kept in a wrong state until the
next X window is focused.
