Looks like a dup of https://bugs.freedesktop.org/show_bug.cgi?id=28341 If you agree you could change the status of this bug to dup. If you pull today's git mesa master you should be able to workaround by running the apps with the env var vblank_mode=0 set, so try - vblank_mode=0 etracer It doesn't work for me from ~/.drirc for some reason. You should still get a different sort of vsync, but only when full screen. vblank_mode=0 changed nothing. Nor does it disable vsync in windowed glxgears. (In reply to comment #4) > vblank_mode=0 changed nothing. Nor does it disable vsync in windowed glxgears. Hmm, Works for my rv670. Did you make distclean, git pull, and build today's mesa master? I guess for glx* you probably need to restart X after as well. |

OpenGL applications (for example etracer) run at 60fps (vsync limit) however there is heavy flickering, or just artefacts on 2D blended elements. Menus for example are only partially visible. Text during game flickers, etc.. Compiz is worse. And even glxgears causes mild flickering. Booting with nomodeset fixs this issue, however performance is very low. ~20 fps on etracer. I tried stable releases of libdrm, Mesa and xf86-video-ati. No difference.
