Description Jessie Berlin 2013-01-31 14:12:39 PST
http://build.webkit.org/results/Apple%20Lion%20Release%20WK1%20(Tests)/r141330%20(8791)/results.html
http://build.webkit.org/results/Apple%20Lion%20Release%20WK1%20(Tests)/r141334%20(8792)/fast/canvas/canvas-composite-alpha-pretty-diff.html

http://trac.webkit.org/changeset/141333 appears the most likely culprit of those 4 revisions

I am not sure yet if there are other Apple ports affected by this.

Yeah, this is my fault, though I don't know why (nor why only Lion).

> Yeah, this is my fault, though I don't know why (nor why only Lion).

This is <rdar://problem/13129639>, which only occurs when using IOSurface-backed canvii on Lion. It reproduces even before my change if you increase the size of the test canvas; I just expanded it to canvases < 100x50.

I'm going to check in expected failing results for Lion.
