The issue seems to occur only when the active display is LoDPI.
MacBook's 2x scaled HiDPI display:

External 1x 1440p LoDPI display:

This is how it's looking when issue occurs on single character - is almost invisible.

Is there a setting to disable the error underlines completely?

this also happens for me on fedora 40, kde plasma 6, wayland on a 1440p 100% scaled display.

Would be really nice if the style of diagnostic errors/warnings was customizable. I believe #365 / #366 made the style hardcoded as wavy, and I can't find any settings related to changing that.

This also happens for me.

I would love to have the error text actually inlay under the line. I hate having to have either a full editor pane dedicated to errors, or hover my mouse over the line
