Are you ever going to improve the PiP? And why you removed the 'redesigned PiP' flag?
The controls are still poor (especially the volume control and the horrible full dimming video on hover).
Additionally the closing cross is black.

Another one issue I noticed is that the reduced PiP produce oversharpened video look.
Compare normal Opera vs One.

*I can predict a question regarding the Lucid mode. But as I mentioned above video becomes overasharpened while reducing it (the smaller is size the bigger is sharpness), lucid is off. I use h264 extension for yotube if that matters.
**It seems more related to Chromium because in Edge there's the same effect.
