Description Jessie Berlin 2011-01-21 12:52:12 PST
It looks like http://trac.webkit.org/changeset/75987 causes transitions/transition-end-event-destroy-iframe.html to trigger the assertion in WebView::paintIntoBackingStore():


Comment 1 Jessie Berlin 2011-01-21 12:53:00 PST
I will add this test to the Windows 7 skipped list soon.
Comment 2 Adam Roben (:aroben) 2011-01-21 12:59:04 PST
Clearly the bots aren't hitting the assertion, since they're testing Release builds. But the test is still failing, obviously, and the assertion might point toward the failure.
Comment 3 Jessie Berlin 2011-01-21 13:03:38 PST
Added to the windows skip list in http://trac.webkit.org/changeset/76384
Comment 4 Adam Roben (:aroben) 2011-01-21 13:13:31 PST
This assertion is firing because the layout update that updateBackingStore did has put us into compositing mode. But we're already far into the non-composited painting process, so we end up hitting the assertion in functions that are part of the non-composited painting process that don't expect to be hit while in compositing mode.

Two of the Windows XP bots (apple-windows-3 and apple-windows-13) have started running the compositing tests. For some reason apple-windows-4 has not. But they're hitting these assertions! E.g., http://build.webkit.org/results/Windows%20XP%20Debug%20(Tests)/r77617%20(24910)/results.html

I removed the assertions in r83852. Bug 58539 tracks reinstating them someday.

As of 2014, this is no longer happening.
