This is what happens when I leave at that internal resution and put fullscren or anything other than 0 in the other spaces...
It seens setting the zoom on Windows 10 has an interference on this app, which will be zoomed as well. Since I put a 25% zoom I thought that downscaling 25% of the monitor's resolution (1920x1080 -> 1440x810) would do the trick, but this resolution is not supported by 7th heaven.
Thing is, everything is way too small without this zoom...
What should I do now? Is there a way to set an exception on windows for this particular program?
