Description: I noticed after upgrading to Mesa 17.1.7, I got a pink overlay on my webcam capture.

Reverting to mesa 17.1.6 fixes this display bug. I'm using nouveau driver if it is important to add.

Additional info:
mesa : 17.1.7-1
xf86-video-nouveau : 1.0.15-2

Steps to reproduce:
1. Get a computer with archlinux testing and a nvidia card.
2. Get Mesa 17.1.7 update
3. Launch any webcam display software like guvcview or cheese
4. Display is broken with a pink overlay :(

See attached screen. Reverting to mesa 17.1.6 fixes the bug. Maybe a rebuild of xf86-video-nouveau is needed?
This task depends upon

Looks like it is a bug in xf86-video-nouveau driver :(

I installed nvidia340xx driver for my old nvidia card (a GeForce G210), and no more pink overlay in webcam capture software with mesa 17.1.7... Ouch!

Please check with rebuilding against core/extra repos if it's working for you with our old toolchain. This could be a duplicate of  FS#55244 .
