https://bugzilla.kernel.org/show_bug.cgi?id=90741 --- Comment #4 from Gustaw Smolarczyk <wielkiegie@xxxxxxxxx> --- There seems to be no substantial difference in 3.19-rc2, 39e7f6f84b3a3aa4520504473f2e2bac1f949ffa or 472db7ab3093bf2a2999f6b5aa64a030466d6f92. The only thing (that may be subjective) is that there seems to be a bit less pauses in final 3.18 and later. (did not bisect that, may be totally subjective) Also of importance can be that I am using 2 GPUs (discrete AMD TAHITI and integrated Intel gen7 (IVB)) in randr 1.4 offloading configuration: xrandr --setprovideroutputsource Intel radeon xrandr --output HDMI2 --mode 1280x1024 --rate 60 --right-of DVI-0 Where: DVI-0 is my main monitor and is connected to TAHITI HDMI2 is my secondary monitor and is connected to IVB The OpenGL window is on the main monitor If that may be the source of these problems, I could disable the second monitor along with the iGPU in order to test that hypothesis. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
