In bug 1418575, many of the current failures are on Windows 10 crashtests, with timeouts on browser startup; logs have screenshots that show cmd.exe running and a small dialog window in foreground, titled "No connection to TeamViewer server". Example https://treeherder.mozilla.org/logviewer.html#?repo=mozilla-central&job_id=153965132&lineNumber=1644 https://public-artifacts.taskcluster.net/VopjYTgLRM2XJTnfhRIkPQ/0/public/test_info/mozilla-test-fail-screenshot_d_kth2.png

:grenade -- Do you know where this dialog comes from? Is it expected? Might this be related to browser startup time outs?

i'll rebuild the win 10 gpu amis without teamviewer today. it was something we thought we needed for gpu instances before but later realised we didn't. in any case getting rid of it should remove the popup. i don't think it would cause firefox to fail to start but it can't hurt to get rid of it and see.

teamviewer removed https://github.com/mozilla-releng/OpenCloudConfig/commit/289627fcf95d9e9ec7cefb559f43f9e411626ed9 deployment in progress https://tools.taskcluster.net/groups/O5keMm4nTyeuxk_OGXHS6Q/tasks/X5EcHTM6SZiyYv19bOYFtg/runs/0/logs/public%2Flogs%2Flive.log

Thanks!
