OK, thanks for testing. I'm very surprised that an unset 
QT_AUTO_SCREEN_SCALE_FACTOR behaves just like setting it to 1. What's worse: I 
personally have it set to 0 here and it seems to work fine on my single 
screen.

Are you using Gnome, Plasma or something else as your desktop environment? I 
really don't understand why this all behaves so differently for you. It seems 
like the update to Qt 5.15 in the appimage changed something fundamentally on 
your specific machine...

It's a packaging bug, I'll have to see what is required to get breeze into the 
appimage too. Apparently the old appimage did that. What are are seeing in 
5.6.1 now is the default Fusion style from Qt.
