Bulk priority update of open intermittent test failure bugs. P3 => P5 https://bugzilla.mozilla.org/show_bug.cgi?id=1381960
Priority: P3 → P5
These started to fail frequently on Windows 10 after bug 1403484 landed.

yes, seeing intermittent failures here: https://treeherder.mozilla.org/#/jobs?repo=autoland&filter-searchStr=mochitest-webgl windows10&group_state=expanded error is the same as the intermittent for mochitest-webgl on windows 7 (bug 1397201), timeout at 330 seconds, screenshots on win 10 show a white screen (no desktop, no firefox window) bug 1403484 was to enable the mochitest-webgl suite on windows 10. i suspect there might be an issue with the test (test_pixel_pack_buffer) since it's failing only intermittently but on both platforms (7, 10).

I think we will track this as an intermittent and disable it if the test fails too frequently.

this started failing I believe after migrating webgl tests from hardware to vm. the screenshot is blank/white: https://public-artifacts.taskcluster.net/PKf0GWGuTXGuxiAmbiFL3g/0/public/test_info/mozilla-test-fail-screenshot_bajn05.png here is a recent log file: https://treeherder.mozilla.org/logviewer.html#?repo=autoland&job_id=134855263&lineNumber=3521 here is a snippet from the log: 09:44:33 INFO - 485 INFO TEST-START | dom/canvas/test/webgl-mochitest/test_pixel_pack_buffer.html 09:44:34 INFO - GECKO(6580) | JavaScript warning: http://mochi.test:8888/tests/dom/canvas/test/webgl-mochitest/test_pixel_pack_buffer.html, line 135: Error: WebGL warning: Exceeded 16 live WebGL contexts for this principal, losing the least recently used one. 09:44:34 INFO - GECKO(6580) | WebGL(000002C298ED5800)::ForceLoseContext 09:44:38 INFO - GECKO(6580) | ###!!!

Possibly the lower performance in VM gets us beyond the 16 contexts, we force dropping a WebGL context and things go bad? Jeff, the max 16 per principal is hardcoded - is that something that is flexible or a hard limit? Maybe send Joel a patch that changes that to a larger number and see if the intermittents go away?
