after going to menu-system-preferences-appearance, I found out: 1) VisualEffects is None 2) Tried to set to normal, the window hangs. tried to set it back to none, the window does not redraw, other windows in the guest system work ok; I did not force close (but I saw that window), so after some time it (the system) rewrote the desktop and all windows, and Alt-Tab now works without hanging the keyboard; 3) setting visual effects to normal is not possible (see screenshot-1).
