Dunno if you figured this out, but this started happening for me too after installing copilot - looks like the two plugins might conflict

[ray-x]

I am using copilot. I do not think it is related. Might be lsp related. What LSP you are using?

[callumacrae]

Why don't you think it's related? It stops happening if the copilot plugin is disabled 😅

I'm using tsserver

[ray-x]

@callumacrae @matteouni Could you check if the issue still occurs in the latest version? Thanks!

[callumacrae]

Yeah, that seems to fix the issue for me! Amazing, I have missed this plugin :D
