Was working ok with old fedora XOrg version (under Fedora 12, it was OK).

I'd like to provide more useful info as whether the bug is in the DRI layer or
XOrg driver but I don't know where to start.

I've tried modifying every EXA options without success. The only stable
configuration is with Accel = false.</pre>
