--- Comment #19 from Sylvain BERTRAND <sylvain.bertrand at gmail.com> --- news: I did dive reluctantly into rpm dev (with debug info). I got my self a xorg server compiled properly for debugging with gdb and its related debufinfo. Only dri2.c:934 make DRI2CanFlip return FALSE. I check my xorg server log and I got: [ 13.506] (**) RADEON(0): Option "BackingStore" "off" [ 13.506] (**) RADEON(0): Backing store disabled -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
