            Bug ID: 172746
           Summary: [CoordinatedGraphics][REGRESSION] Memory hogging since
                    r217214
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Linux
            Status: NEW
          Severity: Major
          Priority: P2
         Component: Layout and Rendering
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: csaavedra at igalia.com

To reproduce, run:

  Tools/Scripts/run-webkit-tests --wpe animations/negative-delay.html --iterations=1000

Same with --gtk. Memory usage for WPEWebProcess will go above 1GB very quickly. Reverting that patch makes WPEWebProcess stay at about 35 MB of RAM.

Zan proposed the patch in http://sprunge.us/JBei but with this patch memory usage increases nonetheless to about 100 MB, so there is still something else not being released. I am not familiar with the coordinated graphics code so this is as far as I can go.
