Spark BUILD IDE unresponsive in Chrome

I have noticed scrolling freezes the Spark BUILD IDE tab. i had an extension for infinite scrolling, but the error still persists after disabling it as well. Any ideas what would be happening?

I am also having this problem. I can generally reproduce it every time if I compile, get an error, then try to compile again without changing anything.

bumping up this thread, today it is happening more and more frequently. All i have to do is scroll up once and then scroll down and then scroll up and the browser window freezes. It worked flawlessly on MS Edge, but then it hung there today as well. Guess it lived its life
