Yes, this is correct behaviour. fglrx cheats a bit there, from my understanding it just does all the pbuffer handling client-side (which won't have quite the right semantics, but it avoids all the complex issues).

Dave Airlie has done some work for a ttm-based radeon driver, but so far ddx only. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
