Unable to view large images on OpenGL video output

Reproduction steps

Try to open large file:

wget -O ~/mars.jpg "https://upload.wikimedia.org/wikipedia/commons/2/28/'Calypso'_Panorama_of_Spirit's_View_from_'Troy'.jpg"
mpv ~/mars.jpg --no-config --loop-file=inf --profile=opengl-hq

Expected behavior

I should see planet Mars

Actual behavior

I see black window instead

I can see the image fine on vo=x11, however, vo=opengl,x11 doesn't fall through onto x11.
Suspected cause - my GPU can't handle GL textures this big, and the error happens too late to be caught by the code that would fall back to x11.

Reproduce the issue with the supplied wget and mpv commands, using the 23123x5093 sample image and the OpenGL error log as a baseline. Trace the vo=opengl,x11 video-output initialization and fallback path, then verify that an oversized image either displays successfully or falls back to x11 without repeated framebuffer errors.
