I've noticed that what's displayed on screen is always slightly behind the input. For example, if I'm using the eraser and move my stylus over a line the pixels under my stylus are still visible... but when I move the stylus away the display "catches up" and the pixels in question are erased.

This effect is always present regardless of what tool I'm using. It does not seem to be memory-related since the correct erasing/drawing still renders even if I remove my stylus from the screen. It's like ArtRage has calculated what stroke to draw, but just isn't refreshing the display.

This happens on both my Galaxy Note 10.1 2014 and my Galaxy S5. Behavior is the same whether I use an S-Pen, wacom pen, or my finger.

If there are any settings I can test on my end to reduce/eliminate this lag, or other information I can provide, please let me know.
