QT: EnableHighDpiScaling is breaking ui on Linux

Open beatreichenbach opened this issue 1 year ago • 1 comments

The AA_EnableHighDpiScaling attribute being set on the QApplication on startup is breaking the UI on Linux Rocky 8.7 on a couple different 2560x1440 screens.

I have not found any reason for this yet, it seems to not accurately calculate size hints with this setting on. The addons run through the dcc QApplications run fine.

Another workaround is setting an environment variable QT_FONT_DPI=96.

I think for now I will use this, until I run into issues with 4k screens. I believe this is only an issue with X and might disappear on Wayland.
