preserve3d-5a.html was added in bug 724614 and has been running well on all platforms including android 2.2 on the tegra boards. last week we turned on testing for fennec on panda board on the mozilla-central branch and have hidden all the reftests due to a series of failures. From this log (https://tbpl.mozilla.org/php/getParsedLog.php?id=18061813&tree=Firefox), we have this failure: REFTEST TEST-UNEXPECTED-FAIL | http://10.12.136.22:30856/tests/layout/reftests/transform-3d/preserve3d-5a.html | image comparison (==), max difference: 4, number of differing pixels: 200

this is still a failure on the panda boards and preventing us from getting automation turned on.

This failure (looks like resampling for some reason) shouldn't be relevant to the actual purpose of the test. I'd be ok with marking this as fuzzy on this platform.

No reports/comments in 3 years, and in that time we abadoned panda boards at mozilla.
