RKats

I have the exact same problem. I'm using Chrome on Ubuntu 20.04 and so far, although it always had some performance issues, it was ok to work with. Since the last update it is almost impossible to work with. When I type I have to wait seconds for characters to appear and I hear the fan of my laptop going nuts. It is painfully slow and sluggish. I have a note with my todo list and it is only around 380 lines of text. There's no reason this should be that extremely slow.
