Does gl*Tex*Image() here imply glGetTexImage() too then you mean? Does reading
from it mean "manipulate"?
Either way, I created <a href="https://gitlab.gnome.org/GNOME/mutter/merge_requests/687">https://gitlab.gnome.org/GNOME/mutter/merge_requests/687</a>
that should avoid reading directly from it. It didn't reproduce with or without
it, so if anyone that can reproduce it can give it a test I'd appreciate it.</pre>
