Help!!! Unity acting weird as hell! Its basically unusable!

Well I opened unity one day to find it acting like this, the window would lag and act weird and stutter as i moved it or moved around in it.

I though maybe it was cause i didn’t update to the latest version but i did it today and the problem persists!

What do i do?

Watch the video so you see what is happening.

I remember having this problem. Try changing the render mode in the edit menu. The one with OpenGL/DirectX/etc. Outside that, try updating your graphics card drivers.

I have the same problem, neither creating/deleting the nvidia profile nor the force opengl trick worked for me. any suggestions?
