[Joel Maher ( :jmaher ) (UTC -8)]

in bug 1658443 I reported a set of file/IO access while running tests on windows10 hardware instead of VMs at AWS.

TEST-UNEXPECTED-FAIL | browser/base/content/test/performance/browser_startup_mainthreadio.js | unexpected stat on C:\Users\task_1596845536\AppData\Local\Temp\tmpudqlbh.mozrunner\wmfvpxvideo.guard before handling user events -

I can reproduce this locally on my windows 10 laptop.

Probably due to the Exists call at https://searchfox.org/mozilla-central/rev/62f6cc5d9c829bc0c6f18e25f93203a98681ac97/gfx/src/DriverCrashGuard.cpp#234
We already had a whitelist entry at https://searchfox.org/mozilla-central/rev/62f6cc5d9c829bc0c6f18e25f93203a98681ac97/browser/base/content/test/performance/browser_startup_mainthreadio.js#558-570 but apparently the I/O is happening later in your case.

The leave-open keyword is there and there is no activity for 6 months.
:jmaher, maybe it's time to close this bug?
