Adobe Acrobat DC 2017 Screen Flicker while handwriting with PEN

Hello,

While I am writing inside the file it starts flickering, specially when I zoom in and write. I change the regedit with DirectInkRegforDC.reg as it was shown here at the official site, but no change at all. The only think that has changed is once I just touch the screen with the pen. its drawing a point like a small circle

Is there another patch to fix this flickering

thanks
