Since upgrading xorg-x11 to 7.1, artifacts started to appear when drawing bars of shaded colors (e.g. window titles). Also, all drawing slows down significantly, causing high CPU loads. Upgrading to xorg-x11-7.2 did not help. This problem only occurs if EXA acceleration mode is enabled. With XAA, everything works fine. I am using a laptop machine with Radeon X700 mobile graphic device, with an external LCD monitor connected via DVI output. The X driver is the open source Radeon driver without 3D acceleration. Reproducible: Always Steps to Reproduce: 1. Install xorg-x11-7.1 or xorg-x11-7.2; check that EXA is enabled. 2. Try more or less any X app with more colourful output, or window decorations that use color shaded bars. Actual Results: All places that should be filled with color shaded bars are instead drawn with random color stripes. Rendering is visibly slow (e.g. Firefox is almost unusable), and CPU usage is very high. Expected Results: Under normal circumstances, color ranges are rendered correctly and very swiftly, with no visible CPU load.

I noticed the exact same behaviour but only today, after upgrading xorg-server to version 1.2.0 and disabling EXA fixed it. While using 1.1.1-r4 and older it EXA worked ok. My hardware is an AMD64 box with an ATI Radeon 9550 (RV350 chipset).
I confirm this bug, I upgraded two computers yesterday, from 1.1.1-r4 to 1.2.0, one is using the nv driver, the other is using the radeon one. The computer using the radeon driver have EXA enable and some apps like firefox are barely usable, top show me that X is eating all the CPU. Disabling EXA or emerge back to 1.1.1-r4 solved the problem.
I can confirm the same behaviour on my laptop, in my case it was also the xorg-server package (and xorg-x11-7.2 depends on it...) I haven't figured out nor tested the EXA configuration effect, but downgrading from xorg-server-1.2 back to 1.1.1-r4 definitely helped.
Well, could you guys also confirm that you are using amd64 architecture like the bug says and not x86? I think it's important for localising this bug.
Sorry, I missed that bit about AMD64. Nope, I'm using x86.

Oops I forgot to notice that, no AMD64 here, X86 for me too.
xserver 1.3 is supposed to have some pretty good EXA fixes in it. 1.3 is expected to be released soonish - probably 1-2 months.
I only did a quick check with xorg-server-1.3. The drawing artifacts have gone, but the problem with the high processor load when starting firefox is still there.
EXA bug still here too with 1.3
i can confirm rendering problems with xorg-server-1.2.0 + R.X700 on x86. for me it is showed mainly by wrong cursor position when working with terminals and generally redrawing of the last line of terminals is mess. cpu load make also impossible to work with some editors. has anybody reported this to Xorg bugzilla ?
The last comment being close to 2 years old, I think no-one still notices that bug anymore. If anyone still has this problem with a fully updated system (xorg-server 1.5.3-r3), please don't hesitate to reopen this bug and to open a bug in FreeDesktop's bugzilla. Thanks
