Checklist

• I have read the appropriate section in the contributing guidelines
• I believe this issue is a problem with polybar itself and not a misconfiguration on my part

• I have followed the debugging guide to narrow down the problem to a minimal config.

Steps to reproduce

1. I simply launched my standard polybar after upgrading from 3.6.3 -> 3.7.0 and it became surrounded with colourful pixels like this:
   

Note, that I'm running Arch Linux with i3 on an asus laptop with an intel video card through a Dell WD19TB dock connected to 2 external monitors.
The issue wasn't there when I disconnected the dock and only used my laptop screen.

I tried downgrading polybar back to 3.6.3 and the issue was immediately fixed.

For anyone on arch, you can downgrade to your cached version by running something like:
sudo pacman -U file:///var/cache/pacman/pkg/polybar-3.6.3-3-x86_64.pkg.tar.zst

Minimal config

I tested without any custom configuration and the issue was there.
