This has happened much more recently but with the same exact hardware as I've used for years. Recently whenever I switch back from a character sheet or literally any other tab to Roll20 with a campaign open the following happens: Chat will "jump" down to the last said message which I can see and it's rather disorienting. Randomly Roll20 will start ignoring the setting I put for sending chat beeps, making me miss relevant information when I'm also looking at my character sheet or spell sheet. An open campaign will become unbearably laggy for moving tokens immediately after, as it in takes 15+ seconds for them to move where my mouse was. I do not have any new extensions installed, disabling the existing ones I have has not resulted in any difference in these multiple issues, restarting my computer has done nothing, I have nothing open but discord, even closing it does nothing. Additionally, I have restarted Chrome to no effect, closed every other tab (even the sheet momentarily) to no effect. I am on Chrome: Version 89.0.4389.114 (Official Build) (64-bit) along with Windows 10 most recent update as of this posting.
