           Summary: [chromium] Force full damage in CCDamageTracker on a
                    tab-switch
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: shawnsingh at chromium.org
                CC: jamesr at chromium.org, nduca at chromium.org,

Steps to reproduce the issue on linux:

1. build osmesa target in addition to chromium
2. run chromium with the following flags: --use-gl=osmesa --enable-partial-swap
3. navigate to the poster circle css demo, which should trigger accelerated compositing
4. open a new tab
5. switch back to the poster circle demo.

Because of partial swap, there will be leftover junk from the previous tab.  The solution is that tab switching should force-damage the entire viewport.
