Completion menu render doesn't get cleared #1932
Description
Make sure you have done the following
- Updated to the latest version of
blink.cmp - Searched for existing issues and documentation (try
<C-k>on https://cmp.saghen.dev)
Bug Description
The rendered completion menu stays on the screen after closing the menu, or the menu becoming smaller.
This happens when completion.documentation.auto_show is enabled and you "type faster" than auto_show_delay_ms (for a consistent repro set it to lower numbers like 100), having other plugins installed (bufferline) and using the nixd language server. After waiting for the lsp to start up and typing {in, you will get some "dead" completion items that are only rendered but can't be selected, and doesn't get cleared.
