Vitest 0.34.4 caused `You appear to have multiple instances of Solid`

Hi peeps, I recently upgraded vitest from 0.34.2 to 0.34.4 and it starts showing for every single test:
stderr | unknown test
You appear to have multiple instances of Solid. This can lead to unexpected behavior.
stderr | unknown test
You appear to have multiple instances of Solid. This can lead to unexpected behavior.
stderr | test name
computations created outside a `createRoot` or `render` will never be disposed
stderr | test name
computations created outside a `createRoot` or `render` will never be disposed
I understand what it means and I am sure I have only 1 version of solid, but I don't know enough to go around to debug this further. I wonder if there is a way get more information to debug this. Vitest 0.34.2 doesn't show that issue. I am using
"vitest": "^0.34.4",
"vite": "^4.4.9",
"solid-js": "^1.7.11"
"@solidjs/testing-library": "^0.8.4",
"vitest": "^0.34.4",
"vite": "^4.4.9",
"solid-js": "^1.7.11"
"@solidjs/testing-library": "^0.8.4",
Thanks,

To be correct I encountered the issues since vitest 0.34.3, nothing updated only changing vitest version.

I have this too on all 0.34 versions (and 1.0 beta) I've tried all the vitest config options suggested here and here

Hi! Have you found a solution yet? With Vitest 1.0.4 the problem still exists.

I think it might be some other things to do with the package manager, It works when I use pnpm but doesn't when I switch to bun

No solution here, but it doesn’t seem to be actually causing any problem. I’d just rather have the peace of mind of not seeing that message. For now I’m just ignoring it.

Does anybody have a config that removes the warning on this super minimal reproduction? https://stackblitz.com/edit/vitest-dev-vitest-xs9lkq?file=src%2Fbasic.tsx
