===== BISECT JOB RESULTS ===== Status: completed ===== SUSPECTED CL(s) ===== Subject : Blacklist CALayer overlays on 10.10 Author : ccameron Commit description: This is causing hangs on 10.10. Forcing fallback to the GL renderer makes the issue go away according to people who have seen the issue. So far all reports of this issue are on the following dual-GPU combination: iGPU: 0x8086, 0x0166 dGPU: 0x10de, 0x0fd5 If this improves histograms, we will try to limit the scope of the blacklist to just this combination.
