Thank you @beegotsy for reporting issues. It helps daisyUI a lot 💚
I'll be working on issues one by one. I will help with this one as soon as a I find a solution.
In the meantime providing more details and reproduction links would be helpful.

The same happens for the tooptip here: https://daisyui.com/components/tooltip/.

This time, on a 3840x2160 monitor, it only connects when using a browser zoom of 67%, 90%, 200%, 250%, 400%.
This may be "more important" (it really isn't), as it's disconnected at the default 100% zoom.

100%

125%

500%

Which OS is this?
This looks like a render issue, because there's no space there in CSS.

@saadeghi thank you for the answer; it indeed seems a render issue.
On my Windows 10 with Chrome 123.0.6312.124 it doesn't work; but on my Windows 11 with 131.0.6778.86 works fine.
