One day an arrow appeared on the curved dashed line showing an angle snap. It was a constant size, and thus obscured great swaths of screen space when zoomed in. It was the same color as the dashed line, and would change color/opacity when I manipulated the interactive appearance settings for angle snaps.
It was a global change: across files, views, layer scales, planes, etc. Then, one day it just disappeared again. As far as I can tell, the arrow is unrelated to interactive appearance settings, cursor settings, highlighting settings, and/or angle snap settings.
What the hell is going on here?
