Strange GPU events
I am wondering if my GPU is going bad. I have never seen the screen anomalies in my 40 years of using Apple porducts. I have had GPUs go bad with streaks, etc. This computer is a top of the line 2013 15” MBP retina, 2.6GHz i7, 1TB HD… It has the VIDIA GeForce GT 750M 2 GB separate GPU and the internal Intel Iris Pro 1536 MB.
- Screen magnification jumped up and down, ending up large in Safari. Had to restart Safari to clear.
- In CAD, the view may jump from left to right isometric, or any other setting. Sometimes screen refresh seems to halt (not because of CAD) . Sometimes line width jumps up or down.
- Sometimes Safari will not open/show a page, such as the home page (an internal file). I get a blank screen, sometimes with a message “couldn’t find file”, or equiv. Has happened on Safari start up.
- Apple support (different problem) during screen share said he could see the splash screen of a different app fading away. One I had Quit just before. I couldn’t see it on my screen.
Is what I am seeing another way the GPU(s) can go bad?
Other than this, the machine works great, but I am afraid the end may be near.
