Interesting, any idea why this might be?

I have deactivated sddm scaling and explicitly set lxqt to 2x scaling. Fusion:  Breeze: 

So it is related to breeze and even occurs without scaling according to @stefonarch.

Do they know about this bug?

So sad

If I get around to it tomorrow, I'll try to report it to breeze.

Unfortunately, I'm not sure if I did everything correctly, but the issue is now also on KDE bugs: https://bugs.kde.org/show_bug.cgi?id=490420
