Bug ID: 426071
Summary: Apps occasionally lose interactivity when switching
virtual desktops
Product: kwin
Version: git master
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
This issue is similar to https://bugs.kde.org/show_bug.cgi?id=426069 , but it
is harder to reproduce, which is why I delayed this report. In addition, I'm
not sure this issue occurs only with XWayland apps. I've also been affected by
this bug for a few months. Both issues might be related.
Sometimes cycling between virtual desktops containing one maximized application
each via keyboard shortcut makes the application be rendered, but impossible to
interact with. This includes keyboard focus and mouse clicks, although
attempting to move it by dragging the titlebar does move it properly. Any
attempts to change its window state (maximize, restore etc) shows the
respective visual effects, but does not nulify this issue.
This issue has most notably occurred with Telegram, WPS Office and Chromium.
STEPS TO REPRODUCE
1. Create three virtual desktops in a wayland session, easiest to reproduce
with them in line
2. Have one maximized application in each of them, wherein each application
shows a blinking text cursor
3. Cycle between them using a keyboard shortcut
4. Unlike the linked bug report, this one requires more attention as you may
only notice it when the cursor blinking stops, and it's more difficult to
reproduce
OBSERVED RESULT
Window can be seen, but can't be interacted with
EXPECTED RESULT
Window can be seen and should be interactive
