All written characters shown as one vertical line

[Rimichu]

When using the new editor, all text is placed in one vertical line. In reading view, text is displayed as usual.

Update your theme and restart Obsidian.
If that does not fix it check if the default theme has the same problem.

Same issue when using default theme.

Check your obsidian.css

In my 0.15.9 obsidian.css I had modified the text width. After commenting that out, the issue went away.

If anyone knows how to set the width in v1.0.0 please let me know.

try no snippets, restricted mode. Restart obsidian.

[zachleach]

to set the width in your obsidian.css do:

body {
    --file-line-width: <width>px;
}
