Description stayingintheshade 2024-07-06 03:05:22 UTC

SUMMARY
When repeatedly opening krunner via the keybind (alt + space, alt + f2, etc) it will begin failing to open, requiring multiple presses of the keybind to show up. It will eventually get to the stage where one must hold down the keybind, rapidly triggering it over and over, to get krunner to appear. Eventually, krunner will not open at all until restart. Note that this ONLY occurs when the text entered into krunner is left as is, any changes to the text field will "reset" this effect.

STEPS TO REPRODUCE
1. Open krunner via the keybind, enter a couple characters of text.
2. Do not change the text. Begin pressing the keybind repeatedly to open and close krunner.
3. Continue until krunner's keybind becomes "sticky" and eventually fails to open altogether.

OBSERVED RESULT
Krunner will no longer respond properly to the keybind, first requiring multiple presses to appear until eventually failing to appear altogether from the keybinds.

EXPECTED RESULT
Krunner opening in response to the keybind consistently.

SOFTWARE/OS VERSIONS

Kernel Version: 6.6.36

ADDITIONAL INFORMATION
At first I thought this could be related to my Nvidia GPU, so I got my friend to test it on an all AMD system, in which he was able to reproduce the bug identically. We both had the same KDE Plasma, KDE Frameworks and Qt version.
I was also able to reproduce the bug with all search plugins except for "Applications" disabled.

I can also reproduce this, also on Plasma 6.1.2 on Wayland. It makes krunner practically unusable for long periods of time. A workaround is to just pkill krunner, but the issue will start happening again fairly soon.

I saw this line in the syslog when the bug occured, I think it is relevant to the bug.

+1
I also find myself in the situation where after using Krunner a few times, the search field no longer appears.
I can only use Krunner again after rebooting  :/
