Thanks for your comment!

Automatically switching the status of this bug to REPORTED so that the KDE team

In the future you may also do this yourself when providing needed information.
Comment 4 Alvin Wong 2021-08-26 14:58:00 UTC 
This looks like it would be a bug with Qt. It gives the monitor with 1280x720 a scaling of 3, which is just plain wrong.

Does it happen if you try with the latest 4.4.8 release AppImage?

Not the "Krita log for bug reports" one, I am looking for the "system information for bug reports" one.
Comment 9 Alvin Wong 2021-08-26 16:40:46 UTC 
I think https://bugreports.qt.io/browse/QTBUG-69136 applies.
