I've seen a lot of stuff about this, but everything I've tried has not helped my problem.
I made a custom 1 px brush using the marquee tool (seems like the default 1px pencil should also work fine though) and I am finding it to be extremely inaccurate on my
MacBook Pro (Retina, 15-inch, Mid 2014) running
Sierra 10.12.6 (16G29)
I think I have the settings configured right with no options turned on in the
brush palette and square pixel ratio turned on under
view -> Pixel Aspect Ratio
The pixel grid seems aligned properly, yet when I go to make a mark using this custom 1px brush, or the 1px pencil tool, I get the following effect in many (but not all) cases:
The pixel will be drawn one or more squares away. What other settings could influence this?
I set up these squares for a sprite sheet using 20px by 20px squares, which seem to have formed properly judging by the grid.
