Steps to reproduce:
Running https://discord.com/app, typing in the message box is clearly lagging behind. It is worse in some channels than others and I'm not sure what the pattern is. This is a regression in 0.99.117, though I'm not sure what version I was previously on. Turning on compatibility mode does not help.
I realize this is a pretty sparse bug report , so let me know if there's something I can specifically do to provide more information. I did notice very high CPU usage while typing (~50%, whereas typing on orionfeedback.com is ~5%), and the sample shows a lot of time in WebCore, so maybe it's a WebKit bug?
