--- Comment #3 from Olivier Churlaud <oliv...@churlaud.com> --- I forgot to say: I'm using the cube animation. Following the advice of crazy on irc, I booted with 'nomodeset i915.modeset=0'. The glitch disappeared (but I don't have any the animation anymore) -- You are receiving this mail because: You are watching all bug changes.
