I can't reproduce this in Nixos 23.11 with foot and terminator terminals.

Here is a gif of my problem:

NixOS 24.05 (Uakari) Linux 6.7.3

I thought I was on latest NixOS. my bad.

The latest stable version of NixOS is 23.11. You running unstable version. It is possible that an unstable version of the distribution is the problem of this bug. Hard to say...

I technically fixed it with a brute-force config approach:

      #for all windows, brute-force use of "pixel"
      for_window [shell="xdg_shell"] border pixel 2
      for_window [shell="xwayland"] border pixel 2
