Opera One (version: 100.0.4801.0) running on fully updated Windows 11.
I can't copy the URL from the address bar, either with Ctrl-C or by using the Mouse double click and select.
A deal breaker if there ever was one.
I have been with Opera since the days of Opera.no.
Also when using paste from the mouse menu, there is distortion. Here is what I copied from "About Opera".

There is a space after "One" but Opera One didn't copy it correctly.
