[Lazarus] autocomplete broken?

[Bernd]

Is there currently some unfinished work going on with the autocomplete
/ dropdown in the IDE? Its behaving very strange and buggy in recent
versions from trunk. I could not find any relevant open bug reports
(maybe because of the wrong search terms).

Sometimes after having typed a few characters if I press backspace the
list is suddenly empty and won't be populated anymore. Also sometimes
it won't complete when I press enter on the selected word, it will
just close the list and  nothing else happens. And very occasionally I
have seen the list suddenly populated with what looks like error
messages (the same error repeated for every list item but truncated at
the end so I cant completely read them, I will try to make a
screenshot when it happens again)

This strange behavior seems to be new, I cannot remember that it
behaved that way a few months ago (but I don't know the exact revision
number, it would take a lot of time for me to find out).
