--- Comment #11 from Alexey Proskuryakov <ap at webkit.org> ---
So something in our tests makes WebGL slower with time, even as all of our processes get restarted. And the culprit may well be some other test or tests, not the ones listed here.

It seems like it may still be a problem on Catalina, as run times seem to be increasing - although they haven't reached 30 seconds yet.

I think that this has to be a GPU driver issue, but hopefully we can isolate and maybe work around it.
