Title: [snb mesa fallback] Slideshow on the stage 18 of Unigine Heaven 3.0 benchmarking after upgrading to Raring Status in “xserver-xorg-video-intel” package in Ubuntu: Confirmed Bug description: Ubuntu 13.04 Raring Ringtail, xserver-xorg-video-intel 2:2.21.6-0ubuntu4, Intel® Core™ i5-2320 with HD 2000 (Sandy Bridge) I've noticed some FPS loss in the games right after upgrading from Quantal to Raring. Then I decided to make a benchmark in Unigine 3.0 Heaven. Average FPS looked the same until the stage 18, when slideshow was started. It took about 2 minutes to get the stage passed, but in Quantal it took only 12 seconds.
