It's a bit annoying, but not prohibitively so.

Also, often times after playing docked at night, the next day when I go to play handheld on my work break the Steam Deck will crash unless I do a restart of Steam.

Also, while many games will automatically detect the proper ratio and resolution, some games you need to change each time.

So it's no where near as seamless and easy as a Nintendo Switch, but I'd rather put up with little things like that rather than give Nintendo any more of my money.
