Describe the bug / provide steps to reproduce it

In settings.json put:

  "wrap_guides": [80],

which under X11 with a 1.5 scale factor renders a line which is extremely thin (see attached screenshot). Note, however, that the indentation lines on the left hand side are fine (1px for the wrap guides and 2px for the indentation lines). This issue does not occur on macOS.

Environment

Can confirm on my end as well, but Wayland with 1x scale factor. The line becomes a lot more visible if I set soft_wrap to preferred_line_length. Otherwise, it's basically invisible.

I just had to set up a theme override to make it darker:

"experimental.theme_overrides": {
  "editor.wrap_guide": "#3333"
}

I don't think this is a design issue (it should just render the line correctly!) it may be an issue with gpui/a linux specific case or the blade render.

I just had to set up a theme override to make it darker:

The problem is that the same override applies on both light and dark variants. Indeed I couldn't see the lines on "One Light" theme, and slightly on "One Dark".

I just changed the themes.

As a guess, https://github.com/zed-industries/zed/pull/38967 could help with this as helped with https://github.com/zed-industries/zed/issues/22711

Zed Preview 0.207 (will be released later today) should contain the change — would be interesting to see if it really helps.

Confirmed as still present in 0.207.
