Re: Bug in 177.80 with glCopyTexSubImage2D, glGetTexImage, glReadPixels
Thanks for reporting this. I reproduced the depth portion of the problem and filed a bug. However, I'm not seeing the color values read incorrectly. Can you clarify exactly what you mean by "sometimes"? Note that if the unified back buffer is enabled, your application cannot draw to pixels in the back buffer (or the depth buffer) that are covered by another window.
