> Summary: Cog VM Causes BalloonEngine Primitive Failure with
> Transparent Polygons
> Description:
> Transparent PolygonMorphs will eventually suffer a primitive failure in
> Balloon. primAddPolygon:segments:fill:lineWidth:lineFill: fails. All
> Macintosh and Windows versions of Cog will produce this failure. I haven't
> tested Linux. Unmodified Squeak 4.1, Trunk and Pharo images produce the
> problem. I was able to reproduce the bug in in original Cog VMs from last
> June. Standard VMs work fine.
>
> I've tried to produce the failure with various colors and alpha values,
> only transparent fills result in failure. I have an application that can
> animate many PolygonMorphs. I ran it all last week with translucent polygon
> without failure.
>
> The morphs don't always fail initially, but will eventually. Just execute
> "PolygonMorph new color: Color transparent; openInHand." a few times and
> play with the morphs, resizing, moving, put windows on top of them etc.
