Oracle set user schema for tables window

Maybe I didn't express myself correctly but - at least in my case - the problems that started this thread are still present.
The oldest version I was using had significantly better performance.
The latest one fixes - in part - the slowness of the incremental search but I get that strange full screen. I say in part because, besides freezing, in the deletion of characters it seems there are no changes.
It is important to clarify that I am testing only on one device (W10 16 gb).
