That's odd, looks like a emacs issue, maybe some bad compilation package or outdated package

Deleted everything in ~/.emacs.d/elpa — no change

It’s not every warning/error that comes through that way

hum, maybe it's some missing face

would be nice to understand if we could know the complete name of that lsp-fly...

Agree. Any idea how to expand that column? Or see the raw data?

lsp-flycheck-warning-unnecessary

maybe changing flycheck-error-list-format variable?

hum, indeed I get the same on my emacs, but not sure it's a problem

I wouldn’t say it’s a problem, but there are packages that rely on more standard Levels

An example (and why I noticed), https://github.com/flycheck/flycheck-color-mode-line

I see, also I don't see a problem marking it on flycheck as warn, but we would need to discuss with more lsp-mode people, so please open a issue there, not sure too if it's possible to change what is presented on flycjec error buffer without affecting anything more

Ok — will do
