No, that doesn't look right. The other bad commits you list below also
don't seem to be related.

You could also bisect between your original working commit (v4.18?) and
the one you want to upgrade to (v5.3?). It's only a few more builds but
might be might give better results.

BTW, are you also converting Gnome from X11 to Wayland. I found that
Gnome's Wayland code is so slow on mgag200 that it's unusable. They
recently added a shadow FB [1] to improve performance, but it won't be
available before Gnome 3.36.

Best regards
Thomas
