How to disable thumbnail previews while hovering over the progress bar?
I suppose you are referring to MacOS? (I don’t have a Mac).
I didn’t see any suggestions threads for this feature; so if this is not a current option (that someone else explains) you might need to create a suggestion thread to ‘officially’ request it.
If you’re talking about another type of device, let us know.
I’ll also create a new suggestion thread for the same.
