Bug ID: 496487
Summary: Invoking task switcher with Show Window enabled hides
windows on all screens even if it's set to filter to
only current screen
Classification: Plasma
Product: kwin
Version: 6.2.3
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: effects-tabbox
Assignee: kwin-bugs-n...@kde.org
Reporter: zor...@gmail.com
Target Milestone: ---
SUMMARY
When holding down the task switcher hotkey (generally alt+tab) with the Show
Window setting is enabled in the kcm, all windows except the "targeted" one is
displayed. This works correctly on a one-screen setup, but if you have two or
more screens and you have set the switcher to filter windows by screen (also in
the kcm), windows on other screens also get hidden while you hold down the
switcher hotkey.
STEPS TO REPRODUCE
1. Have two screens
2. Open window A, B on screen 1
3. Open window C on screen 2
4. With the mouse somewhere in screen 1, press and hold down alt+tab
5. On screen 1, window B is hidden and window A is brought to front, to
indicate that it will get focus when the hotkey is released
OBSERVED RESULT
6. On screen 2, window C is hidden for no reason, displaying the desktop
wallpaper
EXPECTED RESULT
6. Windows on screen 2 cannot possibly be changed to or from because of the
filter settings limiting the current switching to screen 1, so window C does
not get hidden
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: EndeavourOS/Arch x86_64
KDE Plasma Version: 6.2.3
KDE Frameworks Version: 6.8.0
Qt Version: 6.8.0
ADDITIONAL INFORMATION
This also happens when mouseovering miniatures in a task manager if Show Small
Previews is enabled, if Show Only Tasks: From Current Screen is enabled.
I'm not sure what component to file this under, so please reassign it if
necessary.
I'm running Wayland.
