https://bugs.freedesktop.org/show_bug.cgi?id=108979 --- Comment #5 from Timothy Arceri --- Ideally you would try building Mesa from git and do a git bisect to find the commit that broke things. Or if you can do that you could try getting an apitrace [1] of the issue so that someone else can bisect it.
