* Does this also happen with the appimage?
* Does it matter which brush you select?
* Have you custom brushes installed?

Will try (but may take some days)

> * Does it matter which brush you select?

No, tried different simple brushes of various sizes

> * Have you custom brushes installed?

No.

Comment 3 Bug Janitor Service 2020-09-06 04:33:14 UTC

Thanks for your comment!

Automatically switching the status of this bug to REPORTED so that the KDE team
knows that the bug is ready to get confirmed.

In the future you may also do this yourself when providing needed information.

Comment 4 Tiar 2020-11-07 20:23:25 UTC

The backtrace suggests problems with python-qt; can you please say if you are using Ten Brushes script to switch brushes, or maybe did you mean that you changed the size using the Quick Settings docker?

Comment 5 Hans-Peter Jansen 2020-11-08 11:15:21 UTC

Meanwhile, with 4.4.1, I cannot reproduce this issue anymore.

Comment 6 Tiar 2020-11-08 16:08:08 UTC

Great! Thanks for telling us that.
