Until build 1331 all failed for this issue. Then after that build there seems a different error causing VM tests failed.

I didn't really see anything related to web UI changes.

There's a huge number of GPU errors in the chrome logs (ie, [1]). I don't think this is login related; I don't see any login-related changes (but I also don't see any GPU related changes).

+sadrul@ who has been making mojo GPU changes recently (https://cs.chromium.org/chromium/src/services/ui/gpu/interfaces/?dr=C)

I think +oshima@ was seeing something locally, which seemed to have resolved itself? Perhaps a clobber build?

Oh, this may have been fixed by https://chromium-review.googlesource.com/c/552741/ too.

Obsolete.
