--- Comment #3 from Matt Woodrow <mattwoodrow at apple.com> ---
I can't seem to reproduce any failures here, though we're definitely allocating an IOSurface from the WebContent process.

Since this only happens when we don't have an actual image bitmap (and are just allocated a blank backing store), can we just drop hardware acceleration?

Passing RenderingPurpose::Canvas seems like it wouldn't help, since that parameter is only taken into account if we also pass a window via the CreationContext param.
