Shows the colored shading that happens randomly on any frontmost window...usually when scrolling with the mouse wheel
The 2 pixel horizontal line with colors on it, wraps around screen and comes back in from the right. Shows up sometimes on a fresh boot, or after a while (mainly in a safari window when scrolling.)
Shows the 3D "tearing" of the application window. Goes away if I scroll, or interact with the "broken" area in any way. These errors show up on screen sharing app, so I assume they are software.
This is that same window after interaction with the Grab utility (cmd-shift 4). All better.
