This is the diff image: https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20%28Tests%29/r203502%20%2817200%29/platform/gtk/scrollbars/main-frame-scrollbar-horizontal-wheel-scroll-diffs.html As you can see, the expected results is that the window is scrolled to the right, but the actual result is not scrolling the window to the right. Any of this two patches make the test pass: --- a/LayoutTests/platform/gtk/scrollbars/main-frame-scrollbar-horizontal-wheel-scroll-expected.html +++ b/LayoutTests/platform/gtk/scrollbars/main-frame-scrollbar-horizontal-wheel-scroll-expected.html @@ -3,7 +3,7 @@ <p>This is a test for bug <a href="https://bugs.webkit.org/show_bug.cgi?id=122859">122859</a>.

Basically the first patch is disabling the horizontal scrolling on the expected result, and the second one is partially reverting r198269 So, I will mark this test as failing on the test expectations and leave here this bug. 1213166 1 clopez 2016-07-21 10:15:12 -0700 (In reply to comment #0) > So, I will mark this test as failing on the test expectations and leave here > this bug.
