I actually think this is an imgui bug -- downgrading from imgui 2.0.0 to 1.4.1 fixes the error for me. but reporting here til I can figure out a more minimally reproducible example.

Well isn't that strange! I wonder if this is just related to the specific UI element?

[chrishavlin]

ya, i think it is just a bug with the UI element, most likely not really a yt_idv bug.

Fixed by #153
