It's because Tab accepts copilot suggestion, you have to press Enter instead to accept the language server suggestion.

Yes, and what a mess it has been.

Intellisense + Intellicode + Roslynator (extension) combined were really the height of productivity in Visual Studio. Now they've driven a steam-roller over all of that, forced CoPilot down our throats.

I LIKE CoPilot's "chat" interface, and agents are fine too (although Claude in VS Code is tons better), but CoPilot auto-complete is negative value and shouldn't be used.

		Huh I'm the opposite. I find the copilot chat slow and low value compared to ChatGPT. But I use the tab autocomplete a lot. Otoh I disabled all the intellisense stuff so I don't have the issues described in TFA: tab is always copilot autocomplete for whatever it shows in grey.

		I hate the time unpredictability of it. Intellij also has AI completion suggestions, and sometimes they're really useful. But sometimes when I expect them, they don't come. Or they briefly flash and then disappear. What would be nice is if you could ask for a suggestion with one key, so it's there when I want it, and not when I don't. That would put me in control. Instead I feel subjected to these completely random whims of the AI.

		Do people know you can turn copilot off?

Alright, he's just holding it wrong.

Why can't all the suggestions come through the same UI element? That's beyond my understanding.

You'd get suggestions from,

- multiple language servers

- matches from the same buffer/project or sibling pane (tab,window, whatever you call it)

- matches from the dictionary
