SUMMARY
A specific combination of widgets within a particularly thick panel makes
plasmashell freeze with 100% utilization of one CPU core. This started with a
Manjaro update, but notably not the 5→6 one but the one to 6.0.5.
STEPS TO REPRODUCE / OBSERVED RESULT
1. You might want to start fresh with a new user account.
2. Create another panel on the left-hand side.
3. Increase its width to 400 (not sure if those are pixels, so YMMV)
4. In the newly created panel, add the digital clock widget and the media
player widget below.
You might catch a freeze right then. If not, try the following:
5. Kill and restart plasmashell. (I like to do this quickly with Yakuake.)
6. Now you should definitely have a freeze.
7. You can reduce the thickness again by editing ~/.config/plasmashellrc and
changing to something like thickness=200 and verify that plasmashell once again
starts normally.
SOFTWARE/OS VERSIONS
KDE Plasma Version: 6.0.5

ADDITIONAL INFORMATION
