Spice & Virgl machines don't render properly on HiDPI X11
On X11 with hidpi screens (GDK_SCALE=2
and GDK_DPI_SCALE=0.5
), the contents of 3D accelerated VM's screen aren't rendered properly - they take only the quarter of the space, placed in bottom-left corner.
It's particularly problematic because of the fact that while the graphics are scaled, cursor coordinates are not, so it's practically impossible to use mouse.
