Description
Bug report form
- I have done a basic search of the issue tracker to find any existing issues that are similar.
- I have checked that my version is at least the latest stable release available via my installation method.
Describe the bug
On latest main, completions now take 10x as long as on 0.114.1. This may not be an issue on most platforms, but on WSL, the delay can be 8 seconds or more.
How to reproduce
On WSL, on an empty commandline, hit Tab
8 seconds later (being generous), the completion menu appears.
Expected behavior
Menu appears nearly instantaneously, as with 0.114.1 and before.

Research direction
Reproduce the regression on WSL by pressing Tab on an empty command line, comparing latest main or 0.114.2 with 0.114.1. Trace the completion path to identify what causes the delay, then verify that the completion menu appears nearly instantaneously as it did before the regression.
