I've noticed lately that, when my MBP (mid-2015) is idle with a dark screen, I tap the space bar to bring it alive and, momentarily the screen has a vivid "whirlpool" of colours and then my login screen comes up. No big deal, unless this is some sort of clue of upcoming graphic card troubles. That's all I notice. No glitches once I login. Should I be concerned?
