Not corrupt the display.

it's bug #213267, i assume? (black or garbage, window beyond maxmimum texture width)

You'll have to use xrender or -sorry to say- purchase a better GPU.
Even if we would support such, and it's not certain to be possible with GL_texture_from_pixmap, speed would be... "suboptimal" - as it will likely be on xrender for such windows and GPU.

Also it will never be possible to provide any resolution beyond GL_MAX_VIEWPORT_DIMS (do "glxinfo -l" top obtain this values)

preduping, please revert if your limits are bigger than the window (including shadows!)
