I'm sorry to say I'm getting this bug in Calibre 5.43, Windows 10 x64.

I can try to give further information if needed. It does not happen if I click the "magnifier glass" icon, only when I wait for the incremental search to happen.

Attach a book where it happens and what search you did to trigger it
