            Bug ID: 281042
           Summary: [WPE][GTK][Skia] High memory usage repeatedly using
                    putImageData on accelerated canvas
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Canvas
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: aperez at igalia.com

Running a test that repeatedly calls putImageData() on a canvas
many times per frame when accelerated canvas usage is enabled
(e.g. MiniBrowser --features=CanvasUsesAcceleratedDrawing) results
in huge memory usage spikes with high chances of hitting OOM.

A good reproducer is the running any game with the QAOP Spectrum
