Sorry to ping again, is there any acknowledgment that this is an issue? I assume this is not intended behavior. Does anyone know what those lines in my comment do under normal circumstances? Perhaps they can be removed entirely? As I mentioned, there does not seem to be adverse effects from commenting out those lines.

@TomSchimansky , I face the same issue with CustomTkinter v5.2.0. Is there a solution or work around to this issue ? I tried the workaround as suggested by @Nianzu , but that messes up the overall UI size/scaling

Could you provide replication steps? I'd like for my PR to be something stable, so I'll work on it.

I'm getting a similar issue, did anyone figure out a work around for it?

@Nianzu, @Amchanie

• Tried updating customtkinter to the latest version 5.2.2 using pip?

• Could you please provide a sample code which produce this error?

Regards.
