Suddenly, without warning or notice, my dear ole Mac has begun flipping out! Parts of the screen will morph into perfectly shaped triangles or straight edge shapes which will flash, contort, pulse, etc. If I move the cursor to another place on the screen, the distorted portion of the display will change to a new location. As I type this now, the text will jump sideways then straighten back out. I have a screen video of the madness if that helps. I have run the startup diagnostic tests and several virus scans. NADA! This is a QT movie of the screen in action
What does an external monitor show when this happens? If its clean then it’s your internal display having issues.If it also shows the same problem then the logic board has a problem with the GPU logic. Sadly both problems are expensive to fix.
