@andrew84 Nope. The problem is still here on the version (108.0.5067.29) running on Linux. I haven't tried it on Windows in a while, next time I use Windows, I'll try to remember to try.

Opera one: Opera One(version: 104.0.4944.36) on desktop using Linux Mint with Mate, Ver. 21.2

Hitting edge of screen (either right or left) to scroll and pressing mouse button causes screen to unmaximize when I want to scroll. To scroll, you must take your time, make sure the the cursor is not touching the edge of the screen, but planed on the middle of the scroll bar width and then click to scroll. Either this was never tested or was designed by someone who worked on MS Windows at one time. Each new release of Opera lately seems like is taking steps backwards instead of forwards.

I also use Opera on an iPad and doing bookmarks is terrible. You either give up and have hundreds of bookmarks on the speed dial screen or go through gyrations attempting to use mobile, which may or may not record a bookmark in a folder depending on the time of day, the weather, and what mood the browser is in at that moment. You also have no way of moving a bookmark from speed dial to a mobile folder,

I know this should probably be posted as a separate comment, but for what its worth, my two cents on how Opera is progressing backward instead of forward..
The old browser was quite decent, these newer versions not so much. The only time I use it now is a couple of sites that plaster ads all over their web pages, making their content almost useless, but Opera is the only browser that seems to block those ads, the other browsers with all available add-ons fail at blocking those ads those couple of sites.
