hi there,
I have two monitors 4k 27" and HD 24" so I did set up a fractional scaling. Since the I noticed few issues. The VirtualBox app doesn't display any GUI elements inside the main window.
VLC doesn't display any video but I can hear audio.
The default video app does display everything correctly as long as it's not in full screen mode. When I go to full screen mode the app is moved into my second screen and resolution/scaling is changed.
All the problems are gone when I turn off fractional scaling.
