I am using a Lenovo Thinkpad Yoga370 with the included stylus. When I try to draw with the stylus in Illustrator, the screen blinks black for a split second. This only happens when the stylus first touches the screenand won't recur until I lift the stylus and place it down again. I have not been able to recreate using any other apps (Photoshop is fine & all non-Adobe that I've tested).
Thanks for your response. I have checked using Lenovo service bridge and there are no driver updates available for my machine. I have also bought a Wacom Bamboo Ink stylus in the hope that the issue was stylus related but same issue in Illustrator (no issue in Photoshop or MS Paint).
It also seems important to note that this flicker only appears with the Brush, Blob Brush & Shaper tools, all others seem to work fine.
