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.
