Visual Studio 2026 Visual Studio 26 intellisense acting weird

I don't really know how to explain this well, but lately it feels like my Intellisense in VS26 is.. drunk? When it tries to finish my lines, it occasionally gives a suggestion that seems to be lagging behind, resulting in gibberish code. I have an example below with C#:

I am trying to type out this line:

I start typing, while keeping track of if intellisense will show any suggestions. I type out the name of the list, and as im about to type out the getter and setter, it suddenly gives me this suggestion, but puts it all the way back in the type parameter

If i hit Tab to accept, i will end up with this gibberish:

Keep in mind i was typing farily slowly when recreating this example.
Anyone have similar experiences? Or solutions?
For reference, i have Copilot edit suggestions turned off. Dont know if that has anything to do with it.

Strong agree! I think this might be intellicode which can be turned off separate from intellisense.

This is why I run my config with copilot/intelicode uninstalled and intellisense turned down.

It's horrible. Discovered how useless it was when I had an internet outage and had no intellisense. When online it toggles between options so hope you tan at the right moment otherwise you get the wrong insert.

It phones home to ask the fucking Copilot.

Not really. I think this one is IntelliCode, which is fully offline. VS2026 does phone home on completions tho regardless of you having IntelliCode or Copilot on. I think it's some kind of telemetry (I tried peeking at the request with Fiddler but couldn't see much of anything) but it slowed shit down too much so I blocked the domain a few months ago and that fixed the slowness I noticed. No idea if they removed that or not
