I have the exact same problem on Ubuntu 9.04 64bit and 9.10 alpha 3 32bit(livecd). My gpu is an x1800xl. The problem goes away if I use XAA.
Furthermore I tested it with packages provided by Volden's PPA and the problem persists in git. The packages I downloaded are: 1. xserver-xorg-video-ati_6.12.99+git20090710.43db263d-0ubuntu0tormod_amd64.deb 2. xserver-xorg-video-radeon_6.12.99+git20090710.43db263d-0ubuntu0tormod_amd64.deb -- [R520] flash corruption with exa enabled https://bugs.launchpad.net/bugs/335460 You received this bug notification because you are a member of Ubuntu-X, which is the registrant for xserver-xorg-driver-ati. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
