Image scaling issue on linux, high dpi screen.

Not sure if I need a fix for this, this serves more as a documentation so other people may find it. I'll mark it as bug nonetheless.

On a system with these specs:

Operating System: Kubuntu 22.04KDE Plasma Version: 5.24.7KDE Frameworks Version: 5.92.0Qt Version: 5.15.3Kernel Version: 6.5.0-35-generic (64-bit)Graphics Platform: X11Processors: 16 × 11th Gen Intel® Core™ i7-11800H @ 2.30GHzMemory: 15,3 GiB of RAMGraphics Processor: Mesa Intel® UHD Graphics

and a 200% global scaling window setting to support the 3840x2400 screen, Yaak's fonts/UI is huge. (see screenshot with normal fonts and sizes behind the app.

The fix for this is to set this before running yaak.

export GDK_SCALE=1
