Thanks for that, Gert. AFAIK mosts GPUs from the last decade support textures up to size 16384. And ideally all should at least support textures larger than the typical screen resolution they support. If your GL_MAX_TEXTURE_SIZE is 2048 then that's fairly old and uncommon. But certainly we should fix it.
My question is: what is the large actor 2560 pixels in size that the machine is trying to offscreen? It's also a performance bug (for all GPUs) if we're trying to offscreen any actor that large. Even if it doesn't crash, gnome-shell still shouldn't be doing that. Since I am working in the area (https://gitlab.gnome.org/GNOME/mutter/merge_requests/117) the code is still fresh in my mind and I will try to implement your suggested fix.
