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. See here - Unity3D Editor GUI issues - Unity Answers
I have the same problem, neither creating/deleting the nvidia profile nor the force opengl trick worked for me. any suggestions?
