For anyone in 2022 June still experiencing slow loading times, lagging and stuttering when opening new tabs and page rendering in Opera, try tinkering with opera://flags/#use-angle setting. Switching it from the default to OpenGL did the trick.

Whoever in Product team decided to remove this feature clearly does not understand their user base - and also has no idea about ergonomics and UX.
Please, bring back the closed tabs dropdown!
Despite having to go through the Opera switch to Chromium engine when all the good features were just dropped and some after many months or years re-implemented, now we have to be fine with actually useful features that are added and then silently removed? Seriously!
