Hello,
I have an early 2015 retina 13" MacBookPro with some screen problems.
It looks like the memory of the graphics card is not cleared. I see old menu items on the menu bar, I see old windows even after restart...
I wonder if it's a GPU problem or LCD problem? Or is it software?
I tried starting from another HDD: no change.
I tried internet recovery / diagnostics: no change.
I tried resetting of special RAMs: no change.
BUT... it came up out-of-a-sudden OK yesterday! And went back to BAD just few minutes later...
It works OK on the external monitor.
It seems to me like the pointer is rendered perfectly well at all positions on screen.
As a white color is basically all three RGBs LEDs on - it's very strange that pointer is very OK right over a messed up background.. that's what makes me thinks that this could be a software problem... or firmware?
Please, some suggestions welcome.
