@shrey I managed to fix my notification issue it involved me uninstalling opera with user data and then installing the setup from another browser make sure to go to the websites and enable notifications.

Every time when i go in full screen my taskbar thumbnail preview keeps switching I normally have multiple tabs open and when I go in full screen the taskbar thumbnail preview has changed position and I use muscle memory to remember what tab I opened first, because they keep changing its annoying to click on the wrong tab that keeps swapping positions.

If there is a way to stop this from happening please let me know.
