A recent update broke proper screen refreshing in KDE. Often large areas of the screen are not updated (I can see the previous window through large holes in the current window), and text fields are problematic because hitting enter can result in apparent duplicate lines, or missing lines. Reproducible: Always Steps to Reproduce: 1. On machines running an ATI Radeon Mobility M7 (Thinkpad T40, for example) emerge -uavND world && revdep-rebuild && emerge --oneshot xf86-video-ati 2. Restart X and KDE Actual Results: Screen refresh is slow. Often large portions of the screen are not updated, particularly in OpenOffice, Thunderbird, and Firefox. I have to close and open windows or scroll to force redraws. Expected Results: This system is running with compositing and OpenGL hardware direct rendering. It worked fine until my last emerge -uavND world on January 15th. glxgears gives the following peculiar (new) message: Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. Previously, I didn't see this message and framerates were around 400 fps. glxinfo: glxinfo | grep render direct rendering: Yes OpenGL renderer string: Mesa DRI R100 (RV200 4C57) 20090101 x86/MMX/SSE2 TCL DRI2 lspci -k 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility M7 LW [Radeon Mobility 7500] Subsystem: IBM ThinkPad T42 2373-4WU Kernel driver in use: radeon When I create a new user, it uses the software rasterizer renderer by default.

That would be =x11-drivers/xf86-video-ati-6.13.2 since that is stable for you?
Please attach dmesg and Xorg.0.log
(In reply to comment #1) > That would be =x11-drivers/xf86-video-ati-6.13.2 since that is stable for you? That is correct, yes.

Try forcing a different AGP mode via radeon.agpmode=... kernel parameter, or -1 to disable AGP.
(In reply to comment #6) > Try forcing a different AGP mode via radeon.agpmode=... kernel parameter, or -1 > to disable AGP. Disabling AGP didn't work. My kernel settings were the same before the update, and everything worked fine. I wanted to look at the allowed AGP modes, but modinfo radeon doesn't work because the driver is built into the kernel.
(In reply to comment #6) > Try forcing a different AGP mode via radeon.agpmode=... kernel parameter, or -1 > to disable AGP. Have also tried AGP modes (radeon.agpmode=...) 1, 2, 4 and 8. No effect. Does that parameter even work if KMS is enabled?
(In reply to comment #6) > Try forcing a different AGP mode via radeon.agpmode=... kernel parameter, or -1 > to disable AGP. I have also tested with EXANoDownloadFromScreen as an X option, and it had no effect on the problem.
Using radeon.agpmode also breaks power management (suspend to RAM fails and the system has to hard rebooted).
radeon.agpmode as a kernel option does not work, *and* it also breaks suspend-to-ram (this happens regardless of whether it is set to -1, 1, 2, 4, or 8). Setting Option "EXANoDownloadFromScreen" "true" in xorg.conf does not work either, in fact the artifacting is notably worse AND now I get font tearing. Once again -- this worked fine without any of these options needing to be set, with KMS, with direct rendering, before January 15th, when I did the last emerge -uavND world.
What happens now? Is there anything else I need to do? Has anybody been able to reproduce this? I had to disable compositing to make the system usable. Screen refreshes are still excruciatingly slow, but with compositing switched off they don't hang.
Hooray! Updating to keyworded xf86-video-ati-6.14.0 seems to have resolved this problem.
Resolved as per latest comment. 6.14.0 is stable on all archs.
