Description Simon Fraser (smfr) 2013-09-03 15:36:23 PDT
Window resize with a very simple no-JS testcase is terrible after r154967.

People say that tab switching is also impacted.
Comment 1 Darin Adler 2013-09-03 16:09:56 PDT
If the symptom is that bad, maybe we should just roll out!

I assume I just got one of the conditions backwards in the patch somewhere, or removed an early return I should not have.
Comment 2 Alexey Proskuryakov 2013-09-03 16:32:21 PDT
If rolling out, r154981 should be rolled out too.
Comment 3 Darin Adler 2013-09-03 19:03:32 PDT
Is this in release builds, or only debug builds?
Comment 4 Darin Adler 2013-09-03 19:04:40 PDT
I tried to find things I did wrong in the patch, especially ones that could possibly have anything to do with window resizing.

So far, all I found was bug 120659.

No auto? ;-)
