I am using a debug build of WebKit r183016 on OS X Yosemite (14D136) using a Mac Pro with 2.7 GHz 12-Core Intel Xeon E5, 32 GB 1866 MHz DDR3 ECC and AMD FirePro D300 2048 MB. For some reason, I do not see the same failure on the Yosemite WK1 Test bots. Though the Mac EWS remarked about the failing test when it ran tests with the patch for bug #144045, <https://webkit-queues.appspot.com/results/5769191860731904>. The results were uploaded to the bug in attachment #251334. For convenience, I've attached an archive with only the results of the test touch-scroll-to-clip.html to this bug. (*) Tools/Scripts/run-webkit-tests --debug -1 compositing/scrolling/touch-scroll-to-clip.html 1088047 1 ap 2015-04-23 15:38:52 -0700 Initially, I suspected that this could be an ATI specific issue (because EWS bots also have ATI graphics, and regular bots have Intel). But looks like this is a flaky test, I can reproduce that on a MacBook Pro with Nvidia graphics like this: run-webkit-tests --debug -1 compositing/scrolling/touch-scroll-to-clip.html --repeat 100 -f --no-retry --no-show (GraphicsLayer - (anchor 0.50 0.50) - (bounds 265.00 500.00) + (bounds 280.00 500.00) (contentsOpaque 1) ) 1088048 2 simon.fraser 2015-04-23 15:39:22 -0700 Looks like it's just different by scrollbar width (15px). Probably just needs an iOS-specific result. 1088049 3 dbates 2015-04-23 15:41:11 -0700 (In reply to comment #2) > Looks like it's just different by scrollbar width (15px).

For completeness, the test is marked as failing in WK1 for iOS according to <http://trac.webkit.org/browser/trunk/LayoutTests/platform/ios-simulator-wk1/TestExpectations?rev=183154#L1020>. 1088061 5 simon.fraser 2015-04-23 15:50:30 -0700 This seems like a genuine failure (space for scrollbar remains when overflow:hidden is set). 1088062 6 webkit-bug-importer 2015-04-23 15:50:50 -0700 <rdar://problem/20675864> 1088078 7 ap 2015-04-23 16:05:59 -0700 Marked as flaky in r183226. 2169302 8 jbedard 2026-01-05 10:13:11 -0800 Closing old WebKitLegacy bugs as we cut-back WebKitLegacy testing.
