I have a 13" MBP TouchBar, and ever since updating to the latest OS (10.12.3) it doesn't always display the icons. If I touch it they start to appear, sometimes fully, sometimes partially. I kind of doubt it is a hardware failure. Switching between applications will sometimes load a few of the elements/icons, such as swithcing to Safari - it will show the tabs, but nothing else. Anyone else seeing something like this? I haven't looked at the system logs, but honestly, I can't imagine they'd be helpful.
