<p dir="auto">When I'm on my laptop I use 13pt Monaco. When I get to work, I change font to 16pt (because of larger screen, higher resolution) and the preferred line length (80 columns) stays the same. I need to close and reopen all files in order to get it to behave correctly.</p>

<p dir="auto">When the font size is increased and decreased with commands, the wrap guide updates correctly. Here's a video:</p>

<p dir="auto">However, if the font size is modified via the settings view, it doesn't update correct (it does update, but not to the expected position). Here's a video:</p>

<p dir="auto">Notice that the font size is 11. Then I modify it to 14 in settings view and go back to the editor. The wrap guide moved only slightly to the right (not as much as expected). After that I <em>decrease</em> the font size with <code class="notranslate">cmd -</code> to 13, but notice that the wrap guide moves to the <em>right</em> instead of to the left which is what should happen when you decrease font size. This happened because the wrap guide wasn't at the correct position before I hit <code class="notranslate">cmd -</code>, and then moved to the correct position after I hit <code class="notranslate">cmd -</code>.</p>
