Not so sure after reading i915_gem_framebuffer. However, I've implemented a defense against using the wrong framebuffer size: commit 9dae6f9f1f169c228929185a8bd94e82afe92574 Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>> Date: Fri Apr 12 11:01:08 2013 +0100 sna: Flush the scanout cache after resizing the display And ensure that any new scanout allocations make the requested size. It will be worth updating xf86-video-intel.git and seeing if that makes any difference (will be in ppa:xorg-edgers in a few hours).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
