https://bugs.freedesktop.org/show_bug.cgi?id=36596 Summary: Major 2D performance bottleneck (most noticeable with compiz) Product: Mesa Version: unspecified Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r300 AssignedTo: dri-devel@xxxxxxxxxxxxxxxxxxxxx ReportedBy: bluesloth600@xxxxxxxxx Created an attachment (id=46072) --> (https://bugs.freedesktop.org/attachment.cgi?id=46072) lspci -v With compiz, making a new window or resizing a window makes the framerate drop to 2 fps for about 5 or 6 seconds. Running conky makes the frame rate that low most of the time, alternating with brief moments of decent performance. With a more traditional window manager (openbox), a lot of programs (including xterm) freeze briefly every time conky redraws itself, so it seems like that particular problem is not entirely a Mesa bug. Things run smoothly with the fbdev Xorg driver. I tried compiz with the --no-fbo option once, and the framerate stayed at 2 fps until I rebooted. Restarting X didn't help, I actually had to reboot. With the classic Mesa drivers, compiz would sometimes take a long time to render a few frames, but not nearly as often as it does now. I've had this problem with the Debian Mesa packages since they switched to gallium, and with git master (as of yesterday) built with and without --enable-gallium-llvm. I run Debian sid on a Dell Inspiron 1721 with an integrated Radeon X1270. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
