I have the same problem too on Opera One(version: 103.0.4928.34) after the update.
The videos in messenger app are laggy. On the websites too.

I switched to linux last month, but I sadly realized that there is no linux version of Opera GX! Please make it real!

When the messenger is thin I can't switch between the contacts, when I pull it wide the contacts will show up

@kasjonus: thanks, we waiting for it.
