Help with plasmashell crashing and bar disappearing

Hi,

I moved over to KDE Neon from Ubuntu and have been absolutely loving it.

About a week ago the bar at the bottom of the screen started to freeze, then restart and I’d get a handler window pop up. It’s been really annoying and I’d like to try and fix it.

I basically run the same apps all the time, Chrome, Discord, VSCode and a terminal.

This is the info that’s in syslog after the crash:

Is there anything I can do to fix this?

Thanks,

Andy

You can follow the steps to report the error.

There are a few important bugs that will be part of update 6.1.5, and Qt 6.7.3 (if it is released before 6.8).

Chances are those updates will fix your issue, but that’s not a guarantee. You will want to report the crash using the handler if you want to make sure.

Thank you for taking the time to raise your issue.

I’ve run the update this morning, rebooted and it’s not crashed since, so whatever the issue was must have been fixed in the last updates.

Thank you for your reply @meven

Those versions are not out yet, hence the “will”.

Qt 6.8 will be released end of September (or 6.7.3 might come out earlier).
Plasma 6.1.5 will be out September 10th.

Release schedule for plasma can be found at:
https://community.kde.org/Schedules/Plasma_6

Neon backported the fix to kpipewire 6.1.4.

I would encourage to update this package and logoff/back-in or reboot.
