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.

👍 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: #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?
