This is a tracking bug for all reftest failures running with OpenGL accelerated layers on Linux.

Here are the failures that I get on linux x86-64 with NVIDIA driver 195.36 on Fedora 13: [bjacob@cahouette firefox]$ grep UNEXPECTED-FAIL reftest.log REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/box-properties/width-special-values-block.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/bugs/482592-1a.xhtml | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/bugs/482592-1b.xhtml | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/forms/placeholder/placeholder-7.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/marquee/413027-4.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/translatex-1a.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/translatex-1b.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/translatex-1c.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/translatex-1d.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/translatex-1e.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/translatex-1a.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/translatey-1a.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/translatey-1b.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/translatey-1c.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/translatey-1d.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/translatey-1e.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/translatex-2.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/translatey-2.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/translate-1b.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/translate-1c.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/translate-1d.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/translate-1e.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/translate-2a.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/abspos-1a.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/abspos-1b.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/abspos-1c.html | REFTEST TEST-UNEXPECTED-FAIL | file:///home/bjacob/mozilla-central/layout/reftests/transform/abspos-1d.html | [bjacob@cahouette firefox]$ grep UNEXPECTED-FAIL reftest.log | wc -l 27

(In reply to comment #1) > with NVIDIA driver 195.36 on Fedora 13 FWIW this driver is quite old. You seem to be using the driver from rpmfusion, right? They now have a 256.53 version in the testing repository which is said to fix a whole lot of bugs (not sure if relevant for these testcases though)

Although in all my WebGL work I haven't yet hit a single bug in 195.36.

All reftests pass on tinderbox for me now, closing this tracking bug.

What remains to be done before we can turn on accelerated layers by default? The upside-down-flipped-display bug can be worked around by just keeping OpenGL layers blacklisted on these systems. Anything else?
