Created attachment 619828 [details] /var/log/Xorg.0.log Description of problem: Whenever a "spinner" graphic is displayed, e.g. when empathy is connecting to a server, or Evolution is performing any operation, the graphics performance slows down noticeably. The animation for switching to overview mode in GNOME takes about twice as long, for example. Version-Release number of selected component (if applicable): xorg-x11-server-Xorg-1.13.0-5.fc18.x86_64 xorg-x11-drv-intel-2.20.8-1.fc18.x86_64 How reproducible: Happens all the time for me. Steps to Reproduce: 1.Switch to overview mode and back, to see how fast it seems. 2.Start Evolution, which will show a spinner graphic as it fetches mail. 3.Switch to overview mode and back again. Actual results: Graphics performance is noticeably slower. Expected results: No noticeable change in graphics performance. Additional info: I started glxgears, then later started Evolution, to show the effect: 301 frames in 5.0 seconds = 60.178 FPS 300 frames in 5.0 seconds = 59.946 FPS 285 frames in 5.0 seconds = 56.948 FPS 296 frames in 5.0 seconds = 59.082 FPS 269 frames in 5.0 seconds = 53.631 FPS 278 frames in 5.0 seconds = 55.531 FPS 288 frames in 5.0 seconds = 57.568 FPS 301 frames in 5.0 seconds = 60.140 FPS 301 frames in 5.0 seconds = 60.136 FPS <-- started Evolution 150 frames in 5.0 seconds = 29.770 FPS 131 frames in 5.0 seconds = 26.105 FPS 127 frames in 5.0 seconds = 25.245 FPS 123 frames in 5.0 seconds = 24.455 FPS 263 frames in 5.0 seconds = 52.553 FPS <-- here it had finished fetching mail Not sure if this is specific to the intel driver or not.
I blame gtk.
Actually it seems to be fixed now. xorg-x11-server-Xorg-1.13.0-5.fc18.x86_64 xorg-x11-drv-intel-2.20.8-1.fc18.x86_64 gtk3-3.6.0-1.fc18.x86_64
