            Bug ID: 222348
           Summary: [GPU Process] Implement
                    ImageBufferShareableBitmapBackend::bytesPerRow()
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Canvas
          Assignee: webkit-unassigned at lists.webkit.org

The ShareableBitmapCG aligns the rows using IOSurfaceAlignProperty(kIOSurfaceBytesPerRow, ...). This means the default implementation which is "width x 4" is wrong for ImageBufferShareableBitmapBackend.

This will fix the layout failure:
