 Yes, it's certainly due to the "x8" specified above, as raw bitmap access
is not supported in palette-using video modes. The main reason for this is
that I thought nobody used them any longer, when I was implementing support
for this (and that was 10+ years ago, so I think this is even truer today),
but it also probably would be more difficult to support 8bpp than the other

 So I'd advise to retry with the usual x24 instead, e.g. 1600x1200x24 that
I use in the CI workflow file. Or is there some reason to use 8bpp that I'm
forgetting about?
