Opera Turbo is back -just activate it

Die Schnellwahl habe ich deaktiviert, trotzdem startet Opera mit dieser Schnellwahl.
Ich verwende SpeedDial, daher ist die Schnellwahl nicht erwünscht - im Gegenteil, sie blockiert mein Speeddial.

Ersuche euch um Info,

Yes, but with the extension installed - (IDM, Don't care about Cookies, Easy bookmarks, enhancer for YouTube)
I did for testing perposes deactivate the above apps. No change.
Opera Developer 59.0.3160.0

The same problems are with Opera 57

First it was going faster and faster -

What could be the reason for slowing down after 5 days and some installed apps.

Please help!

I'm using the following ext: Roboform, Speeddial, ublock and (now without pulse algorithm) your recommended app smoothscroll.
chromium web smooth scroller has been added with good results of smooth acceleration, I also tried it disconnected. Using smoothscroll only.
Many pages, like FVD Speeddial are still not smooth.

Thank you for helping me.

@acidinmyfridge I tried Firefox - a slow browser, but scrolling and mousing araund is sensational

@acidinmyfridge thank you very much for your response ...so fast! I was using your config but no smooth scrolling is possible.

@acidinmyfridge I am using it - it helps, but not everytime. Can you please tell me which figures you are using in this application?

I installed some of the available "smooth mouse scroller", but not on all pages they function properly.
Basically scrolling ruckels uncomfortably.

Please HELP

Opera is always on top in Windows 10. How can I change this?
