Hey myertveho,
It is kinda hard to tell from your screenshot, but are you working on a single monitor screen?
I tried testing this on my end, but getting the windows to dock on a single screen display like your screenshot is showing. Either way, I tested both single and double screens and attempted to get the editor’s performance to slow down, but I was not seeing the drop in performance.
I might try testing on a weaker machine with less RAM to see if that reproduces the issue, but I will return once my testing has completed.
Thanks,
