Hello! I have a macbook pro late 2013 with intel iris pro on board (high Sierra 10.13.1). When I edit photo with photoshop or standard photo app I face some weird transparent lines across the display. They appear and disappear instantly only when I use a brush tool at the moment when it changes into mouse cursor (please, check the video). I tried to erase SMC and VRAM - it didn't help. I also installed clean copy Sierra 10.12 on external HDD - the problem wasn't solved. Then I tried Mavericks OS and it helped but I do not want to use this version of Mac OS.
Does anyone experienced such a problem?
Any ideas of what can cause the lag and how to solve it?
