Hello, all. I reported an issue to the gitlab
(https://gitlab.freedesktop.org/spice/spice-gtk/-/issues/183), but I see
the readme wants issues sent to the mailing list. I will summarize here:
VM viewers that use spice-gtk do not render properly when running under
wayland with GNOME/Mutter's experimental fractional scaling enabled.
Wayland windows are scaled by rendering at a higher-than-native
resolution (I think 2 x (native res / scaling factor)) and then
downscaled to native res. Spice-gtk reports the higher-than-native
resolution to the VM client, which renders at said resolution. My screen
width is *2256*, but with 125% fractional scaling, VMs report and render
with width (2256 / 1.25) * 2**~*3606*.
Have a nice day.
