Broken Libreoffice (missing menu) and Anki (core dumped) in "current branch"?

Hi all,I am running several desktops on "current". After 1 year without problems I am now stuck and my desktop is not fully usable now (my workflow strongly depends on both apps - Anki & Libreoffice).
I can't remember exact date when it broked but it surely worked with "current" until recently.
After several days of googling,  of trials and errors I would ask if you observed similar issues? Or could you give me some hints to solve the issue or where/how to dig deeper?
My assumption: probably only coincidence with these apps and no common root cause. Libreoffice problem maybe related to gtk+3 issues as reported here https://marc.info/?l=openbsd-misc&m=151053047925572&w=2 <https://marc.info/?l=openbsd-misc&m=151053047925572&w=2>.

Ad versions of third party sw
- amd64 packages from latest snapshot 2018-07-01 (but both issues occurred earlier):anki-2.0.48p1libreoffice-6.0.3.2p0v0

Ad the outputs I  got- see at the bottom

Ad reproducing the problem:- install and run Anki and Libreoffice on "current"- at last I tried to isolate the issue with clean (new installation) "current" (no additional window managers or packages, only pure base) in Virtualbox and installing only Anki and Libreoffice - (un)fortunately the same error messages as from my "current" desktops
- Also tested again on clean "6.3 release" and both apps worked as expected.
Thanks

Regards,M.
