--- Comment #146 from Marc Mezzarobba <marc+b...@mezzarobba.net> --- I too have had a similar issue for a few months. In addition to the suspend/resume scenario described in other comments, very similar symptoms sometimes occur when launching applications such as Firefox and Okular. This makes me suspect that it may be related to some kind of initialization or state change of hardware acceleration. -- You are receiving this mail because: You are watching all bug changes.
