Describe the bug
Hello,
I use the Select from mui-rff and we don't see the border anymore since I updated mui-rff package, We can see it only on hover/focus. I noticed the different between this select and the one from mui/core and it's on the fieldset for the select, we have a white border now.

To Reproduce
Steps to reproduce the behavior:
Use a Select or even an Texfield with any kind of variant from mui-rff.

@bourgeoisadeline Thanks for the report. I think this is more of a discussion than an issue, but if we do find this is a problem with mui-rff, I'll convert back to an issue.

Given that the demo does not have this issue, my guess is that it is something in your theme or overrides. I would try to recreate things with the least amount of changes and then work from there.

@lookfirst Thank you I will see on my side if there's an overrides or something.

I think I found where it's coming from, on @mui/material there is a condition on the theme palette mode, not sure how it works though

[bourgeoisadeline]

I had to add the mode on my Mui theme, by default I didn't have, now it works.
I'm sorry for the inconvenience 😞

[lookfirst]

No inconvenience. Glad you found the issue!
