All menues appear as a mirror of the top left screen, can't see content

Hello,

All menues appear as a mirror of the top left screen, can’t see content.
For example: If i hold over a drop down menu such as “File” close to the UE logo, the menu that drops down will show me a picture of the UE logo and “File”. Moving the mouse down finding menues under “file”, new menu will appear with a new UE logo and “File”.

It’s as if everything is there but whatever I want to click or edit just appear as a mirror of top left part of the screen.

Tried to upload a picture at the bottom of this thread, hopefully someone has any answers. Looking forward to get startet!
