I need to download the attachment and open it locally for the test to work. I can still reproduce this in Chrome Version 29.0.1530.2 dev. It seems the bug repros in Chrome like you say, but not in Safari. I only tested Safari.

If you want to use repaint.js you need to generate a png file too. > LayoutTests/ChangeLog:3 > + Created test for testing repaint rects for regions and some positioned elements. Please clarify what you mean by "some positioned elements". > LayoutTests/fast/repaint/increasing-region-content-height.html:4 > + <script src="resources/repaint.js" type="text/javascript"></script> If you use repaint.js then you should also have a png file for the mac platform and add lines to skip the test on other non-mac platforms where the test is run. If you decide to use the script resources/text-based-repaint.js, then you will have a text output file without the png. From looking at the comment inside repaint.js, text-based-repaint.js seems the preferred way. > LayoutTests/fast/repaint/increasing-region-content-height.html:22 > + <body onload="runRepaintTest();"> Can you add a comment telling what the success of this test looks like? > LayoutTests/fast/repaint/increasing-region-content-height.html:24 > + <div class="zang"> zang? :) 949704 10 216686 stavila 2013-11-12 09:32:28 -0800 Created attachment 216686 Patch integrating reviewer feedback 949754 11 216686 mihnea 2013-11-12 11:26:27 -0800 Comment on attachment 216686 Patch integrating reviewer feedback r=me 949774 12 216686 commit-queue 2013-11-12 12:03:15 -0800 Comment on attachment 216686 Patch integrating reviewer feedback Clearing flags on attachment: 216686 Committed r159132: <http://trac.webkit.org/changeset/159132> 949775 13 commit-queue 2013-11-12 12:03:23 -0800 All reviewed patches have been landed.
