I think the reftest failure log looks exactly like bug 627560 -- it's a 4px difference, with a mismatch at each corner of the box.

But that bug is a 10.5-specific permaorange, whereas this appears to be a sporadic orange on 10.6.  So I'm filing this new bug on it.

This happens on 10.6.2 when layersGPUAccelerated is false.

Comment 23 :Ehsan Akhgari 2011-07-15 13:26:21 PDT
So, these rendering problems look to be a rendering error.  Bug 670338 and bug 670111 have landed around the time this got very frequent.  I'm going to back them out to see if they change the volume of these oranges.  If they do, I guess we can blame this bug on one of those patches...

I backed both of these bugs out, and will keep an eye on the frequency of this bug to see if it goes back down.  If not, I'll reland those two bugs again next week.

I'm not overly convinced there is any correlation. Though if there is any error in my logic I'm quite happy to be corrected! :-)

I've pushed to try the following reftest runs:

m-c tip (includes bug 670338 and bug 670111):
http://dev.philringnalda.com/tbpl/?tree=Try&rev=9e056fe3c757
- OS X 10.6 opt: 0 orange out of 20 runs
- OS X 10.6 debug: 1 orange out of 20 runs
- OS X 10.5 opt: 0 orange out of 10 runs

m-c tip with bug 670338 backed out (ie just includes bug 670111):
- OS X 10.6 opt: 4 orange out of 20 runs
- OS X 10.6 debug: 0 orange out of 20 runs
- OS X 10.5 opt: 0 orange out of 10 runs

m-c tip with bug 670111 backed out (ie just includes bug 670338):
- OS X 10.6 opt: 4 orange out of 20 runs
- OS X 10.6 debug: 1 orange out of 20 runs
- OS X 10.5 opt: 0 orange out of 10 runs

m-c tip with both bug 670111 and bug 670338 backed out: (note try being try doesn't list both changesets, but they are there: http://hg.mozilla.org/try/graph/87912)
- OS X 10.6 opt: 4 orange out of 20 runs
- OS X 10.6 debug: 2 orange out of 20 runs
- OS X 10.5 opt: 0 orange out of 10 runs

Ooops, missed out the remaining try links.

In order (from 2nd to 4th above)...

Comment 27 Ed Morley [:emorley] 2011-07-17 06:11:59 PDT
I've re-triggered a load more reftest runs to try and make the results more statistically significant: (whether the below is sufficient, I'll leave for someone else to decide)

m-c tip (includes bug 670338 and bug 670111):
- OS X 10.6 opt: 2 orange out of 50
- OS X 10.6 debug: 2 orange out of 50
= 4/100

m-c tip with bug 670338 backed out (ie just includes bug 670111):
- OS X 10.6 opt: 9 orange out of 50
- OS X 10.6 debug: 0 orange out of 50
= 9/100

m-c tip with bug 670111 backed out (ie just includes bug 670338):
- OS X 10.6 opt: 7 orange out of 50
- OS X 10.6 debug: 2 orange out of 50
= 9/100

m-c tip with both bug 670111 and bug 670338 backed out:
- OS X 10.6 opt: 8 orange out of 50
- OS X 10.6 debug: 4 orange out of 50
= 12/100

This is just 4 corner pixels being off by 1/255. It's not relevant to the test itself. I have no insight into what might be causing the problem, just some wild guesses. I think we should just censor the corners.
Comment 31 Robert O'Callahan (:roc) (Exited; email my personal email if necessary) 2011-07-17 17:47:37 PDT
