Could you post the stdout.log file from ~/.config/supertuxkart/0.8.2? The
glxinfo output may be usefull too.

It looks that in your case STK still uses the ugly hack with alpha_channel=true
to force srgb-capable framebuffer. And the compositor for some reason doesn't
make the window opaque. Actually it never happened for me on xserver... For
wayland there is wl_surface_set_opaque_region. I will try to reproduce it with
current git mesa.
