Just installed it, works on my kde and niri setups (I logged out and switched to each), copy paste works as well. File manager laggi-ness I didn't notice I don't use it, I use it mostly to type stuff out.
I have never used snippets so unsure about that too, going from command bar seemed to work.
I think it might be bad, but could also be it's not correctly configured maybe try asking codex/claude or something to check if it can fix/fine tune the config, if that doesn't work file issues?
I do suspect it might be working for me cause I got lucky I do see an open issue[1], but given Zed is used a bunch the lack of comments does suggest maybe it's not that wide spread either way not a good look.

Maybe I got lucky?? Does it not auto update on linux maybe I am on an old build... Very suspicious.
