Internal error while (re)rendering widgets

[LeMixer]

customtkinter 5.2.2 Windows 10 Version 10.0.19045 Build 19045

I couldn't reliably reproduce the error, but it gets thrown occasionally whenever the UI dynamically changes, such as pressing a button or showing/hiding widgets.

Is is similar to #1006, but I am using no threads explicitly, but the .after() method.

Update: I've found out that the error gets thrown when wigets overlap when they shouldn't. Resizing my window or intentionally overflowing a text box can cause the error to be thrown reliably.
