I just wanted to add that I see the corruption even with "RenderAccel" to "false" in the radeon section of the xorg.conf file.
I've been experiencing the corruption in dapper for several months now, mostly on epiphany and muine applications but lately (a couple of weeks) it has gone worse and all applications are affected. -- Garbled using open source Radeon driver https://launchpad.net/bugs/38198 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
