I'm using opera on Ubuntu 17.10 Laptop. I switch between using a docking station and an external screen and using only the laptop. For about a week now, the whatsapp/telegram side windows (the icon on the left) launch a full screen of the chat UI and not the regular 1/3 of the screen. When I use the external monitor there is no such issue. I tried restarting opera (closing all the tabs first) and restarting the computer without any luck. Any ides?

I have opera freshly installed on a brand new computer with freshly installed Ubuntu 17.10. When I try to login and sync, opera freeze and eventually I have to force stop the browser. I also have opera installed on two other different machines (Linux mint 17.3, and Linux mint 18.1) where I don't have this issue. This is similar to this report:

I don't have any extensions installed.
