Reported By: glenpaling Assigned To: lewis ====================================================================== Project: Squeak Issue ID: 7598 Category: VM Reproducibility: always Severity: minor Priority: normal Status: assigned ====================================================================== Date Submitted: 01-22-2011 16:44 UTC Last Modified: 01-22-2011 16:44 UTC ====================================================================== 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.
