            Bug ID: 102368
           Summary: Since Archlinux testing migrate to mesa 17.1.7, I got

          Priority: medium
         Component: Drivers/DRI/nouveau

Pink overlay in webcam software

I reported a bug on archlinux tracker : https://bugs.archlinux.org/task/55243

But I noticed that if I installed nvidia-340xx for my old GeForce G210 graphic
card, this pink overlay is no more alive.

Here is my card : 

02:00.0 VGA compatible controller: NVIDIA Corporation GT218 [GeForce 210] (rev
a2)

I noticed reverting to Mesa 17.1.6 fixed the bug, but it is not a long term
solution.

would you be able to git bisect mesa to figure out the exact commit breaking
it? I fear it is my saturation patch, but you never know for sure before
trying.

Another option : just give me a link to your patch I can reverse and rebuild
mesa 17.1.7 without it. It will be quicker and more direct :)

Thanks!

I will try to reproduce on my system first, but this also has to wait today.

If that doesn't fix it, there were two more nouveau patches in the 17.1.7
release:

https://cgit.freedesktop.org/mesa/mesa/commit/?h=17.1&id=75ce282ee243272e937275c6d086b5a391f8ca47
https://cgit.freedesktop.org/mesa/mesa/commit/?h=17.1&id=37e61310e3673de8c23fdb1c1c5181a5e1cdc116

The rest of the patches seem harmless. But I also don't immediately see why
any
of these would be broken. Could well be that some "other" issue gets
triggered
as a result of these fixes.

Please grab an apitrace of the application that reproduces the issue. This will
be required whether one of these patches is determined to be the cause or not.

Looks like it is related to archlinux toolchain. See this bug on archlinux
tracker : https://bugs.archlinux.org/task/55244
