--- Comment #7 from Pierre Ossman <pierre-bugzilla at ossman.eu> --- Anyhoo, getting back to the matter at hand. I set up a new machine so I can more easily do debugging of this. The hardware is instead: 00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Richland [Radeon HD 8510G] Not identical, but should be a very similar chip (ARUBA vs TURKS). I am still seeing the frame rate problem on this machine. It is however not constant, and comes and goes. I am running a lower resolution here, which might be a factor. Also, for some reason I am not getting delays in glReadPixels(). So whatever goes wrong must be happening some place else. I turned on some of the gallium overlays. Not sure if this tells you anything: - Normal playback: buffer wait time of 15k-20k - With glReadPixels(): ~35k - When the bug strikes: jumps to ~50k The frame rate frop and buffer wait time increases are perfectly synchronised every time. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
