This can be reproduced on OSX using --enable-partial-swap on http://css-3d.org/space-cube-2.htm, after clicking "move inside". 607038 1 138194 shawnsingh 2012-04-20 16:37:30 -0700 Created attachment 138194 Patch 607040 2 shawnsingh 2012-04-20 16:37:52 -0700 A note about the unit test on this patch - I wasn't able to come up with a tighter test that allowed us to test exact values of a clipped rect. The problem is that when clipping to w < 0 does occur, the values are usually quite large, and theoretically represent infinity. So, the best I could do was to construct a case where the incorrect un-clipped implementation was very small. Please let me know if you have a better idea for creating a test that covers this change, but I think the test should be acceptable =) 607294 3 138194 enne 2012-04-21 17:12:51 -0700 Comment on attachment 138194 Patch The test looks great!
