So is this how bug reports work with AMD?!
They sit on a forum and mold, unacknowledged?
When I report a driver bug to Intel, I chat with a human being, I receive followups, and they fix the problem pronto.
After investing DAYS into figuring out AMD's bugs, I expect more.
Thanks for nothing.
Hey, I tried doing something similar a few weeks ago, but the corruption I was seeing was my own. Unfortunately GL does not fence for constant updates. So say you have a shared Program which I'm sure you must have, while you do a glUniform on one thread and you modify program state, the other thread does the same glUniform call, which value is the final one ? Completely up to chance. In order to have something like parallel rendering working right you'd have to make sure, in your code that you're never updating constants for the same program at the same time. Another problem is trying to render from 2 contexts to the same framebuffer (even backbuffer) the behavior is usually undefined so it's recommended that you don't do that.
