HiDPI problems under Linux

[KAMiKAZOW]

All icons are blurry under Linux with a HiDPI screen.

I tried fixing the problem myself by applying the common Qt one-line trick from C++ to Python but that didn't help much: KAMiKAZOW@929a5f3

The upper screenshot it the status quo (see esp. the undo/redo buttons), the lower one with my crappy attempt at a fix (the close tab button is sharper but cut off).

Can you try if it is better when you set QT_AUTO_SCREEN_SCALE_FACTOR=0 environment variable?

[KAMiKAZOW]

No difference

#496 is the same as my KAMiKAZOW@929a5f3

Unless other things changed in the meantime, the result should render the same as shown in my screenshot.

Ok, reopening then. Any suggestions for a better fix are welcome.
