As in bug 1095445, the screenshot here shows a few pixels of the lightgreen background (adjacent to border-dots) being slightly the wrong color. In this case, the mismatching dots are all along the left edge & bottom edge of the testcase's content. (all the green pixels that are adjacent to border dots on those extremes.)

This is a different test-slave than bug 1095445 (t-snow-r4-0132 on that bug's first report, t-snow-r4-0086 on this bug's first report), so seems like probably not bad RAM, and probably not a coincidence (because we've been running these tests for years), and now we've got two independent extremely-similar failures on the same day.

I wonder if there's a recent gfx change that could've triggered this.

Also: it's actually the reference case that has the wrong color (barely), in the initial reftest failure in this bug & bug 1095445.

[Daniel Holbert [:dholbert]]

(Also, to clarify, comment 1 & comment 0 here are really the same instance of this failure)
