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?

[KraXen72]

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

Can we please have a setting to disable the red underlines while typing? It is so distracting and frustrating. It's fine for diagnostics and spellchecks to happen with 2 seconds delay after I pause typing. I hate this sort of design. If nothing, at least change the color to yellow or something. Red is just pure bad.

Would it be possible to make it configurable instead of keeping it hardcoded? I personally quite liked the straight lines before, and the style of them changing when working with different setups is really quite irritating

Exactly, there should be an option to have preferred underline scale and possibly style. Currently in my setup the predefined scale is broken.
