Unexpected white window border (every border except top)

[iscaltritti-agilityio]

Preliminary Checks

• I have read and understood the important section above.
• I have searched existing issues and avoided creating duplicates.
• I am not filing an enhancement request.
• I have checked that this issue cannot be reproduced on Mozilla Firefox.
• I have checked that this issue can be reproduced once I removed all my Mods and Custom CSS.

What happened?

When un-minimizing a windowed instance of Zen, the left, bottom and right borders go extra-white.

I can reproduce this when setting up a 4K monitor on the left and a 1440p on the right (regardless of main vs secondary). I assume the same would happen at lower resolutions.

The issue goes away if I switch the positions.

This is the only application I encountered were this happens, and the borders go away when I maximize and restore the window. If I resize, the some of the borders go a bit darker.

Expected behavior

No extra borders should ever show.

Actual behavior

Extra borders sometimes show.

Steps to reproduce

1. Set up two monitors of different resolutions
2. Set the bigger one on the left
3. Open Zen in window mode (not maximized)
4. Minimize and restore the windows

It happens even after disabling all mods and non-default themes and restarting.

Pretty sure it's a Windows-related scaling issue, but I'm hoping something can be done from the browser's side to prevent it.

I no longer see the issue, potentially after a few Windows updates.

In case anybody has this issue in the future: I found no way to fix it but changing the order of my displays, had to get used to moving my cursor to the left to show up on the right.
