But the test is still failing, obviously, and the assertion might point toward the failure. 338283 3 jberlin 2011-01-21 13:03:38 -0800 Added to the windows skip list in http://trac.webkit.org/changeset/76384 338285 4 aroben 2011-01-21 13:13:31 -0800 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. 338409 5 aroben 2011-01-21 15:54:26 -0800 <rdar://problem/8901509> 345468 6 aroben 2011-02-04 07:00:12 -0800 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 385748 7 aroben 2011-04-14 07:22:59 -0700 I removed the assertions in r83852. Bug 58539 tracks reinstating them someday. 1063131 8 bfulgham 2015-01-21 12:12:15 -0800 As of 2014, this is no longer happening.
