           Summary: [EFL] [WK2] fast/dom/vertical-scrollbar-in-rtl.html
                    makes fast/regions tests flaky
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: yael at webkit.org


The test fast/dom/vertical-scrollbar-in-rtl.html is calling window.resizeTo, which resizes the window and the viewport. When the test ends, the viewport size is 500x500. We do not resize the window back to 800x600, so our gl viewport stays smaller, and that leads to the garbage we occasionally see in fast/regions tests. These tests fail if they run on the same worker as fast/dom/vertical-scrollbar-in-rtl.html . 
The attached image shows the problem.

A patch is coming.
