Stage.contentsScaleFactor always 1 on Linux (HiDPI support)

[pol2095]

Description

Stage.contentsScaleFactor always 1 on Linux (Ubuntu 20 and Fedora 34 : display scaling is 200%) HiDPI support for 4K screen

I added in the app descriptor : <requestedDisplayResolution>high</requestedDisplayResolution>

my app is very small vs the same app on Windows or Mac.

I found a workaround here, but it's not perfect.

xrandr -s 1920x1080
/path/to/executable
xrandr -s 3840x2160

Thanks.
