I experience the same problem in PHPStorm - but not in iTerm. Don't know what could cause this.

I tried reproducing in a similar environment (code-server 3.11.1 in Ubuntu using Windows and Chrome 95 locally) but so far no luck reproducing; the tab completion works normally for me.

My steps:

sudo apt install zsh
sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
source <(kubectl completion zsh)
kubectl get pods<tab>

If you have SSH access can you verify it does not happen in a regular terminal?

this also happens for me as well sometimes on code-server version 3.12 running on Ubuntu 20.04.3
the webpage is loaded with Firefox v93.0 on Ubuntu 20.04.3

I have had it happen even worse than the example gif. Can't get it to reproduce right now but I don't remember changing anything

Yes, Autocomplete works fine with mobaxterm ssh client with zsh shell and bash shell.
Basic autocomplete supported by bash shell also works correctly in code server.

Does this still happen with the latest code-server? Maybe it was a rendering issue. A few other rendering issues seem to have been resolved in 4+.

If the problem persists, it might be worth trying this in your user settings:

    "terminal.integrated.gpuAcceleration": "off",
    "terminal.integrated.fontSize": 15,

@echuber2 thank you for following up and confirming! And thanks for posting that user settings snippet workaround (if the issue still happens). In that case, I'm doing to close this for now. If it still happens for others, comment here and we'll reopen.
