I generally just type Ctrl-L to clear and redraw the screen. For most
filetypes I prefer fdm=syntax, so maybe something's different with
fdm=expr.

I notice the improper folds most frequently when I've just added another
branch to a conditional (e.g. turning something with the structure
if(1){}else{}
into
if(1){}elsif(2){}else{}
) but I can't seem to come up with a good minimal case. I'll try to do
that next time I notice the problem.

In case they affect anything, I also still have the following mappings
in place:

aug NoInsertFolding
au!
au InsertEnter * let b:oldfdm = &l:fdm | setlocal fdm=manual
au InsertLeave * let &l:fdm = b:oldfdm
aug END

They have their own problems (referenced in another thread), but are
better than the madness of folds changing mid-insert.
