When I started up today, my computer had a very slow and deliberate refresh of anything on the screen, like it was loading everything on 56k dial-up.

One of the most egregious examples was on launchpad, where each row of app icons loaded with a visible scrolling line going from the top of the screen to the bottom.

Has anyone seen or experienced anything like this?
 
Could be a video card chip issue. They all seem to have issues 13 and 15. The Iris 540 is a fast GPU so it should not lag.
