So I switched to KDE Plasma 5 from XFCE a few months ago and absolutely love it! The developers and designers have done an excellent job of making a desktop environment that has the customizability of XFCE but with a more modern look and feel.

So anyways, I am using Kubuntu 19.10, But I recently noticed that according to the "Show FPS" Desktop Effect, my computer is dropping frames when I do simple things like snap a window, open a program, resize a window, Speed Test essay writer or open the app launcher. It rarely seems to drop below 50 FPS, but it is annoying me. For whatever reason, it doesn't seem to drop any frames when I try Kubuntu from the installation media. I am also using the proprietary Nvidia driver.
