Description

[James Graham [:jgraham]]

Bug 1532580 tries to update wpt to a revision that includes 800x600 reftests. This turns out to cause a lot of intermittents with blank screenshots. It seems like the problem is we are opening the window at 600x800 rather than 800x600 which causes us to notice that the window is the wrong size. This then causes us to not apply the DRAWWINDOW_WIDGET_LAYERS flag. In the absence of that flag the screenshots are blank. I suspect it's intermittent because after opening the window we try to resize it, but if that resize is async it may or may not happen before the test.

Also note that the fact that it only happens when the window is freshly opened means that the results depend on whether the browser just restarted, which in turn depends on whether the previous test passed or failed.
