Ubuntu Studio 20.10 is now based on KDE Plasma, exactly as Kubuntu 20.10: well, in Fusion 12, with 3D graphics acceleration enabled (with default settings and maximum shared memory), both have corrupted graphics, with various dynamic (also “flashing”) distortions and false colours, mostly in the KDE menu, but also in the menu bar and desktop; while with 3D acceleration disabled, everything works normally, albeit of course a little too slowly to be usable. Experimented on new VMs, created with default values as far as graphics is concerned; and with open-vm-tools-desktop correctly installed. Of course, 20.10 Ubuntus are not yet officially supported, but just to report the problem…
