There were UX bugs though it’s been some time so I don’t remember all of them.

One of them was that when I pressed the windows key and searched for an app sometimes it just wouldn’t react at all, and I had to press it multiple times or use another way to launch an application.

Also the default file manager would often hang up for no apparent reason.

The desktop widgets would change their position every single time I logged in and would even disappear.

Edit: just remembered a hilarious one that took me a lot of time to figure out what was happening. If I had my second display turned on while logging in, the visual scale would always set itself to a ridiculous value like 1% or something and everything would be too small to do anything. I had to turn off the display every time I would log in. Before this I didn’t even know the PC could detect whether a display is turned on or off.

No matter what I set the scale to in display configurations, it would get fucked if I logged in with a second display turned on.
