Does it help to customize which-func-non-auto-modes to add the major
mode you are using there?  Or maybe customize which-func-maxout to a
small value to get the same effect in any mode?  I'm asking whether
this helps because it's unclear to me whether doing so will avoid
blocking redisplay, if and when which-func finally becomes active.

If the above doesn't help, I guess some changes to which-func could be
in order, to avoid blocking the first display of a buffer for such a
long time.  So in that case we shouldn't close this bug report yet.

Thanks.
