--- Comment #2 from Kimmo Kinnunen <kkinnunen at apple.com> ---
Thanks for the report. 
I think this has the same root cause as bug  237113.
In order to workaround, you can try if you can rework the rendering so that it does not need the `autoClear = false`. I.e. use `autoClear = true`.

Leaving this in until fix for bug 237113 is testable.
