Resolution Note:
Thank you for submitting the bug. Because this issue is only reproduced when using specific Chrome flags we will be unable to fix this explicitly. The issue seems to be related to the general performance capabilities of the browser's main message loop. Future Unity releases will include general performance improvements, so we encourage you to update the game to newer Unity versions when they're available.
