Description Chris Guillory 2011-04-29 17:23:52 PDT
This issue was discovered while investigating http://crbug.com/80616. Looks like the call to endPlatformPaint should have been removed in this changeset 41978. http://trac.webkit.org/changeset/41978/trunk/WebCore/platform/graphics/chromium/FontChromiumWin.cpp.

Comment on attachment 91771 [details] Patch OK. How do we test this? Recently there was a RIAA added for GraphicsContext::save/restore which helped get rid of a bunch of bugs like this in the cross-platofrm code.

Comment on attachment 91771 [details] Patch Seems we either need a test or an explanation of why testing is impossible in your ChangeLog. I don't think we can test printing with DumpRenderTree. So if printing is required to test this, automated testing may be impossible.

One way to "test" would be to have the non-printing case fail (in debug mode) when this bug occurs. I have a Chromium change out for review for that. http://codereview.chromium.org/6949012/
