I'm having a very strange lag when navigating in the scene viewport using the WASD/QE keys, there is also a very big (relatively) delay when you are moving to the left (using A key) and suddenly switches to the right, the camera stops for a moment then starts moving, it is also stuttering a lot when moving around. I started a new scene and only created a cube in it, deleted the light but seems like this issue has nothing to do to any of this, I also maximized the scene viewport and decreased the unity editor window sized and tested to see if it had something to do with the resolution but the issue persisted, switching to the fastest settings on the quality settings also changed nothing and switching the rendering path to forward also didn't had any effect. What could it be? This behavior is annoying me for a long time now... Edit: when you enter play mode the issue is no more, but when you exit the play mode the issue comes back. Edit 2: When I was going to record the issue in fraps the issue stopped while the fraps was recording, it looks like fraps was forcing unity to render the fps that was setup in fraps (29.97), but when I stopped recording the fps showing for the scene view was around 1-14. It is like unity is refusing to update the scene view even though I am holding the right mouse button over it. Edit 3: Restarting the editor ceases the issue (still with some stutters but not a big deal), changing the layout scheme makes the issue come back.
