Bug ID: 452315
Summary: Switching virtual desktops causes keyboard shortcuts
to stop working until click
Product: kwin
Version: 5.24.4
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: abulhair.sapa...@gmail.com
Target Milestone: ---
SUMMARY
I have a single activity with 4 virtual desktops side-by-side and I have
"switch one desktop to the left/right" mapped to a shortcut. When I use this
shortcut to switch to an empty desktop, it will (almost) always cause keyboard
shortcuts to stop working, and so I can't continue using those shortcuts to
switch desktops or go back, *until* I click on the desktop. I'm not exactly
sure but it seems like plasma "loses focus" when this happens.
Interestingly, this does not happen if there is a window or application open on
the new desktop, and I wait for a bit. However, if I switch quickly between
desktops that have open windows/applications, the keyboard shortcuts stop
working after a few switches. I'm guessing it has to be faster than a few
hundred milliseconds.
I think this may be related to my Xorg configuration, since I have a monitor
connected via displayport and an A/V receiver which is then connected via HDMI
to the same NVIDIA GPU. In order to run the monitor at 144Hz, I needed to put
them on different X screens, so KDE runs on the primary X screen and doesn't
manage the other display. If I instead have KDE manage both displays, the
keyboard shortcut problem doesn't occur.
STEPS TO REPRODUCE
1. Use keyboard shortcut to switch to empty desktop (no windows or applications
open)
OBSERVED RESULT
In (almost) all cases, all keyboard shortcuts stop working, as if plasma has
"lost focus."
EXPECTED RESULT
Keyboard shortcuts should continue working as normal.
