Mid 2015 MB Pro Retina 15 inch. El Capitan.
Short flickering and a slightly shaking screen when i use the cursor to move items and when i zoom in and out in Adobe CC apps.
Connected to a Thunderbolt Display worse more often and more random.
Did all the stuff: clean install, pram etc etc. Went back to Yosemite and Adobe CS. Same problem.
Then i noticed that connected to my old Cinema Display all above disappeared!
Now i'm working on my Mid 2015 MB Pro Retina screen with the mini display cable from the Cinema Display in the macbook's Thunderbolt 2 port.
And all the flickering and shaking screen is gone! I can't understand the correlation and it's not the solution cause i can't drag the
Cinema Display with me all the time. With this comes a new phenomenon: a overheated macbook and a fan that doesn't stop.
Can someone make chocolate out of this? Thanks!
