Same here so I did a bisect.
There are 2 problematic commits, making the bisect a bit more complicated.

The first one has already been solved by d6053bf2a170.
The second one is 811fa9a79cf ("mesa: unreference current winsys buffers when
unbinding winsys buffers"). 

Using master + this commit reverted: no more corruption in chromium.
