My desktop has been doing lots of strange things lately.
On startup I can't see the mouse pointer. I can only find it by how it affects the icons at the bottom of the screen. Once I have opened a window I can see the mouse.
All the desktop icons have disappeared.
Firefox only opens a small window and I can't close it.
Firefox, Chrome and VLC have no enlarge minimise or close buttons in their windows.
The open apps are not appearing at the bottom of the screen.
I don't know what's happening. Maybe all those wonderful updates have done something unhelpful.
Any suggestions?
