Package: xserver-xorg-video-intel Version: 2.12.0+shadow-2When I run an OpenGL game, the brightness suddenly turns to dark, then a few seconds later it's set back to normal.
I play the game, then quit it.When back to Desktop (Gnome), brightness is dark again, and I have to manually set it to bright with FN+Up keys. Happens since today, after updating xserver-xorg-video-intel amongst other packages.
