There were 33 failures related to this bug in the last 7 days. This occurs on Linux opt, asan and debug. Reftest analyzer is not showing relevant data for this. Here's an example of the log: https://treeherder.mozilla.org/logviewer.html#?repo=autoland&job_id=142446545&lineNumber=9413 Analyzer example: https://hg.mozilla.org/mozilla-central/raw-file/tip/layout/tools/reftest/reftest-analyzer.xhtml#logurl=https://queue.taskcluster.net/v1/task/NOp_4tiZTLm5sldksv3FVw/runs/0/artifacts/public/logs/live_backing.log&only_show_unexpected=1 :jet can you take a look at this since it spiked in the last few days?

This test is already a fuzzy-if within the pixel thresholds reported in this intermittent failure (max difference: 32, number of differing pixels: 33) fuzzy-if(winWidget||gtkWidget,32,34) fuzzy-if(skiaContent,1,28) http://searchfox.org/mozilla-central/source/layout/reftests/bugs/reftest.list#601 I'd normally just add more fuzz, but that won't fix this if the reftest harness is intermittently ignoring the specified fuzz parameters. Mats: can you tell what's going on here? Thx!

Line 9412 says: "INFO | REFTEST fuzzy test (0, 0) <= (32, 33) <= (1, 28)". I'm guessing both gtkWidget AND skiaContent are true and we selected the latter fuzzy-if. I find "azureSkia":true,"skiaContent":true in the log which seems to indicate that's what happened.

I looked into this intermittent failure a bit. In my environment(Ubuntu 17.04 + XVFB), I can reproduce this phenomenon with low probability. (about 0.0199. [4/200]) If I move the 2nd condition to primary condition, this test passes always. (Try count is 20000) (In reply to Mats Palmgren (:mats) from comment #30) > Line 9412 says: "INFO | REFTEST fuzzy test (0, 0) <= (32, 33) <= (1, 28)". > I'm guessing both gtkWidget AND skiaContent are true and we selected the > latter fuzzy-if. > > I find "azureSkia":true,"skiaContent":true in the log which seems to > indicate that's > what happened. A refests use last fuzzy-if condition if we specify multiple condition and these condition is true.[1][2] [1] https://searchfox.org/mozilla-central/rev/30ead7d1ae5bf95b8bc0fd67b950cd46ca05e32c/layout/tools/reftest/manifest.jsm#202-206 [2] https://searchfox.org/mozilla-central/rev/30ead7d1ae5bf95b8bc0fd67b950cd46ca05e32c/layout/tools/reftest/manifest.jsm#384-387 So I think we should modify fuzzy-if condition order of this test in this bug. Mats: This fuzzy-if condition has modified in bug 1179543. In this test environment(i.e. azureSkia:true and skiaContent:true), I think we can use the gtkWidget condition, Is this correct?

Yeah, maybe we should just swap the order, like so: fuzzy-if(skiaContent,1,28) fuzzy-if(winWidget||gtkWidget,32,34)

(In reply to Mats Palmgren (:mats) from comment #32) > Yeah, maybe we should just swap the order, like so: > fuzzy-if(skiaContent,1,28) fuzzy-if(winWidget||gtkWidget,32,34) Thanks. Try: https://treeherder.mozilla.org/#/jobs?repo=try&revision=ed95c7e42c57c8cdfeea795e294473e72f3c7e7d Assuming a green try run and my environment, I guess this change is effective to this bug.
