temporary performance issues when prism.dirtyopts set to false

[Jose Martinez]

Hello,

I notice performance issues when prism.dirtyopts is set to false.  But it only happens during the first minute or so of game play.  The animation is not smooth, it looks as if it has a low frame rate.  But after a minute the animations becomes smooth for the rest of the program execution.  The poor animation performance returns if I restart the application.

Is this a known issue?
 
thanks
