Well, if it uses core X11 fonts, then text is rendered in software, which could certainly explain at least some of the issues. If you're using a non-anti-aliased font in the terminal, does switching to an anti-aliased one improve terminal performance? > The problem appears to be affecting any application that moves > substantial amounts of graphics data around - so scrolling a > large amount of text in a terminal window causes visible flicker. > Equally, rapidly moving a window around the desktop causes very > obvious lag as the X server struggles to keep up, with ghost images > being left around for a short period afterwards.

Then I don't suppose Option "ColorTiling" "off" helps, as I don't think that could have been enabled with 2.6.32. Basically, you need to try and narrow down further what exactly made things worse for you. Is it the new X server or driver? ... Though, if the bad performance is accompanied by high CPU usage of the X server process, getting a profile with sysprof or oprofile might give an idea of what's going wrong. Please make sure the xserver-xorg-core-dbg and xserver-xorg-video-radeon-dbg packages are installed for this. -- Earthling Michel Dänzer | http://www.vmware.com Libre software enthusiast | Debian, X and DRI developer -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
