Heads up > little glitch in the latest version

I'm seeing some graphyx anomalies flipping between apps and Sonar that sometimes force me to kill and restart Sonar to recover in the latest version (no saving is possible... can't even stop the recording in progress).
 
It isn't happening often, but it's there. Nothing repeatable.
 
For those who care a ton about stability, caution (don't stop on the tracks).
