Looks like we hang during startup for 5s. Some kind of GPU/window manager bug perhaps?

I think this hang might be manifesting itself on these two bots:

https://build.chromium.org/p/chromium.gpu.fyi/builders/Linux%20Release%20%28New%20Intel%29?numbuilds=200
https://build.chromium.org/p/chromium.gpu.fyi/builders/Linux%20Debug%20%28New%20Intel%29?numbuilds=200

There are frequent hangs during browser startup that are affecting many tests. We are seeing similar symptoms on some of the waterfall and CQ bots, though fortunately less frequently. It might be the case that the ultimate cause is a bug in the GPU process that is causing the browser process to hang.

 Issue 591127  has been merged into this issue.

Raising to P1. As far as I can tell this is happening on multiple platforms and is affecting the commit queue.

Unrestricting access.

+ericrk@ who is pixel wrangler.  Eric could you investigate?

I will try to reproduce the Mac issue reported in  Issue 616629 .

vmiura@ Can you please set the priority/milestone and find an owner?

Reducing priority as I think the issues on the commit queue turned out to be something else.

I'm not sure when I'll have time to look at this, but looking into general GPU hang issues.

OK. In the interest of not leaving bugs hanging around arbitrarily let's close this as WontFix (not reproducible). I don't think we've reproduced the submitter's specific problem, and we aren't seeing browser hangs upon start at this point. (The problems that were seen at one point on macOS were machine misconfigurations.)
