Mix up when in Search notes mode

[TX3 1]

When I'm in the Search notes mode of Evernote Desktop for Windows 10, 

I now have to scroll a little for the note to refresh.

Just now, the contents of one note was copied into an old note, completely replacing the contents.

This dumping was without warning, as though the scrolling mixed up the contents.

Does anybody see this problem?
