InputField caret too big in world space canvas

Hi everyone,

I've been struggling with this for a while and I cannot find any relevant help so far, so I give a try here. I'm using a TMP_InputField in a World Space canvas and I get everything to work fine except that the caret is way too big and I don't know how to fix this. See this screen :

This is what I have with a caret width set to 1, which is the minimum. The only workaround I found so far is to set a custom color for the caret and make it transparent by settings its alpha value to 0. But it turns out that not having a caret is way more annoying than I thought.

I've checked every scale-related possible issues and I think everything is OK. And what makes me think everything is OK is that everything works fine except this damn caret. The text itself appears good, the windows scales up and down the way I want it, etc.

Any hint to solve this ? Thanks in advance
