I have Fusion 11.5 and loaded Fedora 31. After setting HiDPI mode with 200% scaling, the background shows only white. Everything else renders fine - menu bar, applications, etc. But the background only shows white. Also, when I do the virtual desktop (expose? I don't recall) thing where it shows all the desktops at the top of the screen on the Mac, that desktop shows white while all the others render properly. Any suggestions?
Update: This also happens in Ubuntu 19.10.
