I'm on a Macbook Pro 15 2018, sometimes there is this strange red line that appear. In finder, in chrome, in itunes, in different applications but always on top or bottom. Before I make a partition and install High Sierra to see if it is mojave the problem, anyone seen this on his computer?
I have to take a picture with phone because as soon as I move the cursor disappear.
