Comment 2 Robert Jenner 2021-04-06 19:21:07 PDT
I have reproduced the timeouts at BigSur Debug ToT using the following test:

run-webkit-tests webgl/2.0.0/conformance/glsl/misc/shader-uniform-packing-restrictions.html --debug --child-process=1

I'm currently working on bisecting and verifying a regression point.
Comment 3 Robert Jenner 2021-04-06 19:30:43 PDT
I believe r275088 is the change that caused the timeouts:

Will follow up tomorrow morning.
Comment 4 Robert Jenner 2021-04-06 19:31:44 PDT
I was able to reproduce the timeout in r275088, but not in r275087.
