I also have seen some weirdness of late, but I'm still on F31.  I had yaml files indented with sw=4 and my foldmethod=indent.  Now I have to open the fold twice, once for the invisible fold that seems to be implied as if sw=2 and one more to get the real thing.  If I reformat to use 2-space indents the folding works like I'd expect but something changed.  I've also gotten lots of pain with certain key combos that were solid for ages.  Ctrl-6 to swap buffers % and # now must be Ctrl-Shift-6 for vim, though the former still works in gvim.  I have a mapping for <C-E> :nohlsearch<CR> that I've used for over a decade to un-highlight a search.  That no longer works in vim or gvim.  Until I'd found that I figured something in konsole had changed.  But once gvim revealed weird issues I figured it must be more of a vim thing. Now seeing this message, I'm becoming even more certain.

I understand better now my problems with my mappings.  Above, I said I had a mapping for <C-E> :nohlsearch<CR>.  In actuality, this was ^E :nohlsearch<CR>.  Both should work but only the latter now only works with vim; gvim shows the mapping with :map but I can't make it trigger.

I still don't know what's up with the yaml indenting.  I'll have to check on the cindent setting that's been brought up recently.  I also don't understand the new Ctrl-6 behavior, but I suspect that's konsole that's changed.
