An update on enabling EXA-acceleration in xserver-xorg-video-radeon 6.9.0+git20081003.f9826a56-0ubuntu2:
There are small corruption issues, and so it is right to still default to XAA.
The issues are not big, however:
* If I use a bitmap-font in Gnome-terminal (yes, "Fixed 6x13" is my favorite of all times), there is annoying glyph-corruption. This never happens with fonts that are anti-aliased, so workaround is to not use bitmapped fonts in Gnome-terminal.
* There is occasional small corruptions around check-box-widgets in web page forms when scrolling the page in Firefox. I've only seen this on pages with a large number of these boxes, like a typical GMail inbox.
* Very rarely, there is slight corruption below the mouse cursor, but only for certain applications. I've seen it in Emacs and when running a remote Firefox using X-forwarding (on RHEL5).
I plan to post proper bug-reports of these issues when I get around to it. And of course, if anyone knows about work-arounds for these issues, please do tell !
Also worth mentioning that I have tried the latest GIT-snapshot of the radeon-driver, and it works fine, but none of the issues above are fixed.
