I rebuilt Mesa Git master. A problem I was previously having only with KMS is now also there with UMS: KDE (4.5 RC2) is extremely slow and "laggy" when minimizing/restoring and moving windows. For example, the window minimize animation that previously took under 1 second to complete with even and smooth animation, now takes about 3 or 4 seconds, and the speed of animation - even though smooth - varies extremely. The window begins to "zoom out" towards the task bar very, very slowly, then picks up a bit of speed again, then slow again, etc. Moving windows is also very broken. When grabbing the title bar, the GUI freezes for a bit, then you can move the window around, but while moving, it freezes again every 1 or 2 seconds. Everything is really glitchy, making the desktop unusable. As I mentioned earlier, this was happening when using KMS in the past. Now it also happens with UMS. I'm using: xf86-video-ati Git master on a Radeon HD4870. kernel 2.6.35_rc5 Mesa Git master libdrm Git master X.Org server doesn't matter (happens with anything between 1.8.0 and Git master) I reverted to the previous Mesa Git build I was using before (I'm using Gentoo, so I first created a binary package before emerging latest Git so I can revert back to it.) I don't know which Git revision it is; is there a way to find out? Must have been about a week or since I last rebuilt it from Git.
this kernel patch may help: http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commitdiff;h=29508eb66bfacdef324d2199eeaea31e0cdfaa29
