[SOLVED] X screen painting problem

I'm not sure which forum to post this to, so here goes...

Since about three days ago, intermittently the X screen is not always painted correctly.  This can happen in any application -- I've seen it in Firefox, gedit and liferea, as well as in the lxpanel display of open apps.  Sometimes just a few characters are affected; e.g., all "t"s will be changed to an unrecognisable squiggle.  Other times large parts of the screen are sort of "smeared" around.  (See half-size image below, from a gedit session, for an example.)  Usually I can cause the screen to be repainted correctly by switching to another app, and then switching back, but sometimes I have to log off and log back in to resolve the issue.

Any ideas what could cause this?

Re: [SOLVED] X screen painting problem

I am having this same problem. I just re-installed arch on an old laptop, which had been running arch flawlessly before but hadn't been updated for a while. After the installation everything under X windows runs very slow even xterm takes a while to update one line and I'm having the same painting issues.

Perhaps our problems have a related source?

Here's my xorg.conf...http://pastebin.com/fcb3b0a9

Identifier  "Card0"

        Driver      "radeon"

        VendorName  "ATI Technologies Inc"

        BoardName   "Radeon Mobility M6 LY"

        BusID       "PCI:1:0:0"

Re: [SOLVED] X screen painting problem

I've been seeing the same thing as your screenshot since the latest xorg update.. mobility radeon x300 here.

I'm assuming it's an upstream issue, but doesn't hurt to mention it here.

Re: [SOLVED] X screen painting problem

I'm getting the exact same issue, it is related to the Xorg update a few days ago. Not sure what graphics I'm running since I'm away from that comp for now.  I'm probably going to downgrade Xorg for a while.

Re: [SOLVED] X screen painting problem

I just noticed there are a few threads on xorg-related issues in the Pacman & Package Upgrade Issues forum.

Re: [SOLVED] X screen painting problem

Yay! Disabling KMS fixed the problem for me. Others with an Ati may try this too...
