Hey zmo@, I see you've helped on out bugs around this area in the past - mind taking a look at this one on reassigning to someone who might be familiar? Thanks!

We're working on replacing the old copy of Mesa used for these tests by SwiftShader.

This is not fixed, just that ClusterFuzz is able to ignore these crashes properly now!. Mac was having missing source paths which now show up and we ignore based on #0 and #1 with mesa is ignored.
