6d0f6cb Revert "Fix [3513017] in lockscreen but showing empty launcher (live wallpaper) only" 6154412 Revert "partially fix [3306150] HTML5 video with H/W acceleration blackout (DO NOT MERGE)" 37c2a37 fix [3408713] Dialog window invisible sometimes It looks like there is a surface leak, it's unclear where it is. Without those reverts, this would cause a leak of the associated buffers which is far more problematic. this change might hide the surface leak.
