Does it happen on other browsers too?

I'm not seeing the trailing artifacts on Firefox or Safari, but I am seeing the stopwatch flicker into the upper-left corner.

Possibly related to https://github.com/phetsims/decaf/issues/57.

Testing the current website production version on mac/chrome. I see the flicker to the top left, but no more trail of artifacts.

Oh, well I just discovered this is also buggy when running the java -jar quantum-wave-interference.jar. So this is not a CheerpJ/decaf problem at all.
