Yea I've tried to work around it by just clicking on close ice first but I find if I don't click in super short increments my character just kinda does a little derp dance trying to walk off the ice. I just wish normal ice wouldn't have this interaction when you have slipping immunity since that is the only negative aspect of it and with slipping immunity it isn't harmful.
Cursed ice I view a little differently, since the chill and freeze goes through magic armor you would want to path around it but the game does that automatically unless you are standing on it already and in that case any walking even to get off can freeze you so it's still a pretty hostile surface. I'm actually not even certain if you can even slip on cursed ice so it may be treated already as a completely separate surface than ice in general. I tend to just use one of the jump spells or terrain transmutation to keep myself safe there.
All in all though I just wish they could make an invisible tag or something that makes it so that when you have slipping immunity then you treat normal ice as an ordinary walking path since it effectively is just that. Or alternatively allow us to turn off the auto-pathing because when you have significant magic armor outside of combat most surfaces aren't really a threat, so the shortest path through them would still be nicer than the intricate dance of the derp that my character does trying to choose between my manual input and it's ingrained auto-path instinct.
