Have you experienced the problem with drawio?

Yep it's a bit hard to show on screen recordings but the entire system feels like it downclocked the CPU/GPU to a 10/th of its actual cpu once you got an instance running.. even more so when you have more than one draw.io instances open. You gotta have them visible / on screen and not minimized as macOS seemingly only re-renders/draws the shadows for visible ones however.
