Hi guys,

a really annoying problem is nagging me on -current:

H.264 videos in my browser don't show up correctly. It looks like after a keyframe happens the video just garbles itself into a green mess until another keyframe comes by. I can't see anything and videos are unwatchable:

I have a Thinkpad X201 netbook with Intel HD graphics (5th generation, Ironlake/Arrandale chipset).

This happened during one of the changes in -current a few weeks back. I already downgraded xf86-video-intel, to no avail.

Before I try recompiling and downgrading mesa I'd like to get some input from you guys. Does anyone else have this problem or any idea on what to try to fix it?
I want to watch YouTube without SMPlayer again.

Edit: Alright, I tried Mesa 11.1.2 and 11.0.8 now - the problem exists with both versions.
So either it's not a Mesa bug or something has changed in the mesa.SlackBuild recently.

Edit #2: Rebuilt Mesa without vdpau support. Still have the problem. I'm absolutely clueless right now.

Edit #3: A-ha!
When I start Chromium without libGL support the problem goes away. So it is a problem with mesa.

Mesa? MAybe not.
if you rebuilt mesa without hardware acceleration and browser has problem.
MAybe it is browser problem?

The green videos happen both in Firefox and in Chromium, so I don't think it's a browser problem.

I believe it is related to VAAPI. When Chromium starts up, it pulls the decoding capabilities of my video card with VAAPI.
When I run
it works fine. Looks like my Intel HD cannot decode some H.264 videos properly, although the driver claims it can.

I can live with the above solution now. Maybe I will file a bug.

Still don't know why it worked before and suddenly stopped working, though.
