Created attachment 110333 [details] YUV to RGB shader Hey, I'm a developer on Roundabout - Alexander pointed me to this bug report. It looks like our YUV to RGB shader is failing to compile properly on these drivers. I've attached the source for this shader to the bug report to help you track down any compilation issues, let me know if there's anything else I can attach to help track down this issue.
Since this is actually a Cg shader, it's hard to say for sure. Is the error log from the driver available? Depending on the GLSL version that is used, it is probably these lines: float y = yuv.b *255; float u = yuv.g *255; float v = yuv.r *255; Many GLSL versions do not do automatic type conversions. If you change these to float y = yuv.b *255.; float u = yuv.g *255.; float v = yuv.r *255.; it should work. Some of the other constants may need similar treatment. You could also request a GLSL version that does automatic conversions (1.20 or later).
