Description When a window containing a CTkScrollableFrame is resized, the entire UI lags.

Steps To Reproduce

1. Create a window, either tkinter.Tk() or customtkinter.CTk()
2. pack a CTkScrollableFrame into the window
3. resize the window

Additional context This bug is observed to happen all the time on Linux, but much worse only sometimes on Windows. I haven't tested it on macOS.
