We will run into this when we land bug 583499

Comment 2

This should hard block.

Comment 3

Not sure how to reproduce the problem now....

Rob, I thought you'd fixed this before :(

[Mike Shaver (:shaver emeritus)]

I can reproduce it easily by running twitter on my wife's MacBook (too old to get accel, though it's running 10.6).  Let me know if there's anything else I can do to help, she is...expressing her displeasure to me.  (She moved off b9 because of the similar problem there.)

This is a problem for any BasicLayers-using computer, likely only with plugins and/or <video> open.

We can't release any beta with this bug. We currently think & hope that Bas's fix to bug 627399 will fix this bug, but if it doesn't, we can back Robert O'Callahan out, and that will fix it too.

and twitter (as mentioned by shaver) and the steps to reproduce from bug 627399.

But would be great to have a testcase here

We found a similar problem on Android (bug 627087) which was caused by:

http://hg.mozilla.org/mozilla-central/rev/a18080aa75d6
Robert O'Callahan — Bug 621601. Part 1: Change empty transaction API to
EndEmptyTransaction. r=bas,tnikkel,a=joe

We had to turn on double buffering. Maybe we could backout our fix now that bug 627399 landed

This seems to be fixed, but please reopen if not.
