I am using a MACbook pro and Photoshop CC. If I am using an adjustment layer and maupulate the sliders my screen blacks out for a moment. It does not matter if I use a pen from my Wacom or the trackpad on my MacBook. If I am using the arrow keys it does work fine, but that is not very helpfull. Lightroom works normal. this problem occurs recently I think three weeks ago. I have 16 gb(?) RAM.
Can anyone help me?
