Inlay hints multiply when using VSCode action "Rust Analyzer: Restart server"

[Heinenen]

While writing some rust, I restarted the language server with the "Rust Analyzer: Restart server" action and encountered a bug.
My "workflow" to reproduce:

1. Restart r-a server
2. Comment out a line
3. Save file
4. Uncomment same line

The bug is reproducible for me 100% of the time, even when I wait longer after restarting the language server.
Restarting the server multiple times increases the number of inlay hints multiple times (also seen in gif).

rust-analyzer version: 0.4.1132-standalone (567a5e9 2022-07-18)

rustc version: rustc 1.62.0 (a8314ef7d 2022-06-27)

PS: When using the "Developer: Reload window" action, the inlay hints don't show up at all unless I change something in the file (with or without saving it). If you think that is worth another issue, I can file one for that as well.

I am experiencing the same thing with auto-completion, hovers, and other things. Duplicate items start being displayed. For example:

I'll chime in and say that I'm also experiencing this. It's like "restart" behaves more like "start another."

odd, I can't reproduce this at all, not the duplication of inlay hints, nor inlay hints not appearing after a reload until i change the file ...

+1 also had this happen to me recently, but only once and I couldn't make it happen again so I didn't report yet

[Heinenen]

I am also experiencing the same issues as @leighmcculloch, I just didn't notice it.
Another thing that appears multiple times is the outline and "Go to Symbol in Editor (Ctrl + Shift + o)"
If it helps, I am using Manjaro KDE with the open source build of VSCode.

Just to make sure, how did you install the extension? Actually, what extensions do you have installed?

[leighmcculloch]

I didn't install rust-analyzer manually. It was installed via the vscode extension.

[lnicola]

How did you install the extension?

@Heinenen seems to have a recent build, at least of the server binary.

I see this on macOS for Arm and VS Code 1.69.2 (although I ssh into an x86 Debian machine).

[Veykril]

This is very odd, I'm on VSCode 1.69.2, windows and cannot reproduce it with the latest server. When executing the Restart Server command do the inlay hints stay and a new set appears once restarted, or do the hints disappear and then re-appear duplicated?

Note that RA runs on the remote side. You should check the version number(s), just in case.

[leighmcculloch]

I am on VSCode 1.69.2, but I've seen this behavior on previous versions too.

I switch back and forth between the release and pre-release versions of rust-analyzer, and I'm not 100% confident, but I think I'm only seeing this on the pre-release version of the extension, v0.4.1136. I don't see this behavior on the latest release version of the extension, v.0.3.1131.

[Heinenen]

I installed my extension by downloading the .vsix from the marketplace and then installing it inside the Extensions tab inside vscode.
I have VSCode 1.69.2 aswell (for linux)
