I'm trying to use virgil OpenGL acceleration on ubuntu 20.04.2 both host and guest, but I get only 1/4 of the screen no matter what I do:
It's an intel i7 11th gen, Iris Xe GPU (Dell XPS 13)
UPDATE: as pointed out below, the problem is with scaling. How can I make this work with scaling on?
virt-manager
does not seem to support this. Maybe you should try GNOME Boxes?
