I'm running into this problem where snap to grid has to be turned on for every single layer and switching between images it also has to be enabled. What is also weird is I must enable it with ctrl + shift + ; or else it doesn't work. Any know what the deal is here. Enabling it in the interface doesn't even do anything.
Okay I've figured out what the problem is but I don't have a solution. When snap is turned on I can snap to grid with a marquee select, when snap is turned off I can snap to grid with the paint brush, anyone got any ideas this is extremely annoying having to enable and disable snap to select vs move pixels.
