Debian Trixie on 6.2.5. IIRC, this is was happening on my laptop during 5.27.5 as well.
I dug around a bit but can’t pinpoint the issue:
balooctl is disabled due to some issues on 5.27.5 previously, but AFAIK, that is not related?
Here are my installed spell checking pkgs:
$ dpkg --get-selections |rg -N spell
aspell install
aspell-en install
hunspell install
hunspell-en-us install
ispell install
libaspell15:amd64 install
libhfstospell11:amd64 install
libhunspell-1.7-0:amd64 install
Some of the spell-check-related config below may have been missing initially. I made some changes after trawling for krunnerrc files on github, but nothing that I threw against the wall seems to have stuck. Here’s my current config:
