Summary: Regression: Weird flickering of content is seen while playing the game. (was: Regression: Weird flickering of content is seen after playing the game.)
The "flickering" is not indicative of a graphics problem but of a JavaScript problem. The displayed world position keeps bouncing back and forth between two or more locations. It could be a math error or ???

I went to chrome://extensions and enabled developer mode and then viewed developer mode for the game. This showed various errors:

It is quite possible that the problem is ultimately a bug in the game itself - depending on undefined behavior - but determining that is outside of my area of expertise.

However it is not clear that these are related to the issue. In particular, while testing with 64.0.3278.0 I could not reproduce the problem. Can you still reproduce it? If so then capturing the developer tools console output when it happens could be helpful in isolating the problem and deciding who to assign it to, if anyone.

Clearing RBS label until we are sure that that is necessary.

Note:
Rechecked above issue on latest canary version 65.0.3285.0 (Official Build) on Windows(7,8,10) and its still reproducible
