Dev server game page crashes when on another browser tab

I am developing a game API. I am flitting between my game page and the my game's "Game Settings page" as I am editing my code. After a short period of time where the game browser tab is not the active tab the game page crashes on Chrome with the  message "Aw snap something when't wrong while displaying this page". I have also noticed that even if I don't wait for the page to crash when I make it the active page it remains frozen for a long period of time when I return to it. Please put it back to the way it was before. I am using chrome version  72.0.3626.96 (Official Build) (64-bit)

Also chrome's memory usage and CPU usage starts to climb dramatically when the game tab isn't the main tab. You can observe this in task manager.

Hello Jack T., We apologize for any issues you may be encountering. So we can rule out any other potential issues, we ask that you please carefully work through these steps of our guide to  Solving Technical Issues . Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome  and  Firefox. Step 2: Ensure that there are no extensions/addons interfering with Roll20 Please disable  all  add-ons/extensions. Step 3: Clear your cache If none of the above succeeds, please thoroughly work through  Step 4 .  (Don't forget the complete Console Log!) Thank you!

Okay I cleared the cache on the browser and that didn't work. On the chrome developer console window I was getting lots of these messages every second Swapping <a href="https://app.roll20dev.net/images/character.png" rel="nofollow">https://app.roll20dev.net/images/character.png</a> to /images/character.png app.js?1548199937:538 setting src app.js?1548199937:538 Swapping <a href="https://app.roll20dev.net/images/character.png" rel="nofollow">https://app.roll20dev.net/images/character.png</a> to /images/character.png app.js?1548199937:538 setting src adinfinitum I solved the problem by deleting my game and rebuilding it from scratch. I am so happy this wasn't my production game and just a game I use for testing scripts.

Hello again Jack T., Glad to hear that you were able to find a solution to your issue. I am going to close and resolve this thread. If you have any further issues, feel free to start a new thread.
