Steps to Reproduce:
After above, most of the time the 2nd ruler at the left window does not show up. This only started manifesting on newer version (no problem with older version)
It seems that there are general issues with multiple rulers when the zoom level is -1 depending on how wide an editor is.

Thank you for confirming. The show-and-tell screenshot is very informative RE: how to get around this. Unfortunately, in my environment the left pane doesn't show the other ruler no matter how I resize the width. What I end up doing (to get a side-by-side code experience) is open the 3rd/last editor pane and minimize the width of the left most. Ugly solution but it works.
Please keep the bug open until there's a permanent fix. Thanks for the support.
I think this is how Chromium deals with a 1px vertical line when it is zoomed below 100%. My recommendation is to not use window.zoomLevel.
Not using window.zoomLevel as a solution is not enticing in my case. The reason why I use it is because all the window component of vscode are a tad big for my taste (icons, folder or solution view, etc) and although I like to see them all the time so I can navigate through my files, they are just taking too much space.
I will only go back to 100% zoom level if there's a way for me to customize font size of the other elements of the window that is not tied up to the editor window's font.
Nevertheless, thanks for the follow up.
:+1: I would also like a way to customize the font size of other elements of the window. Please create an issue for that so I can upvote it :). The zoom level is a cheap trick that causes multiple problems, such as this one, or breaking antialising, etc.
I'll create one. Thanks for the recommendation.
Here is @johncruise's followup ticket: https://github.com/Microsoft/vscode/issues/10605. How do you guys feel about allowing the ruler width to be styled via themes? Could be a quick fix for the relatively small group of users who are affected by this.
The same happens when using for example the Zoom Level on Windows to something like 125%. Some rulers are 1px wide and some are 2px wide depending on how the rulers align with the screen pixels:

When Windows is set to 125% and window.zoomLevel: -2:

Thanks to the help from @fj128 in discussions in #28542 , we have a plan on how to workaround this.
With the technique discussed in #28542:
When Windows is set to 125% and window.zoomLevel: 0:

When Windows is set to 125% and window.zoomLevel: -2:

Why is this closed? I have no idea what to do about this. Is it possible to configure the thickness of the ruler?
Not a maintainer, but from what I understand, it is closed because it has
been fixed and now we just wait for the next release.
