Display is flickering with gray stripes when tilting it.
A couple of months ago my display started to flicker with gray stripes, both vertical and horizontal when tilted at some degrees. With time this has happend more frequent and has gotten even worse. Now it's permanent, though the stripes switch places when the display is being tilted.
When the MacBook is connected to an external display, the flickering can't be seen on that one.
What's wrong with my computer?
Is this a good question?
