[01:39] <Sarvatt> apw: crap, missed your pings yesterday, no it wasn't me you talked to
[01:40] <Sarvatt> i'm sure x-x-v-intel 2.99.907 "fixed" your corruption problem by neutering the speed of your gpu
[01:41] <Sarvatt> that was http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=9289e2c56b7f0cc78c5123691ad96611f0e04bed
[01:43] <Sarvatt> the upstream bug looks like they have no clue how to fix it under SNA, https://bugs.freedesktop.org/show_bug.cgi?id=55500
[01:43] <ubottu> Freedesktop bug 55500 in Driver/intel "[sna gen4 w/a] corrupt rendering (including wrong rendering of characters and flickering on redraw)" [Normal,Assigned]
[01:45] <Sarvatt> SNA can be disabled on a per GPU generation basis at compile time, worst case disabling it on gen4 might be in order for the lts :)
[01:45] <Sarvatt> but really if you can file a bug about it the upstream intel driver dev (ickle) triages all the intel bugs on launchpad and will see it
