I first noticed this happening when running Java (JOGL) Processing.org OpenGL code.
However since running some independant OpenGL tests, it seems to a general OpenGL rendering issue.
Code (and applications) seem to run ok, it's just that there's no actual rendered output.
To fix, I've tried:-
- uninstalling any suspect programs, updates, or drivers
- reinstalling my graphics hardware drivers
The issue remains.
Intel 965/963 Graphics Media Accelerator (onboard Intel X3100 graphics adapter)
Any help would be greatly appreciated.
