Odd message in debug console, and WARN: COPY_MODE on window titles

[rowleya]

Windows Version

Microsoft Windows [Version 10.0.22631.3880]

WSL Version

2.3.12.0

Are you using WSL 1 or WSL 2?

• WSL 2
• WSL 1

Kernel Version

6.6.36.3-1

Distro Version

Ubuntu 22.04

Other Software

Anything graphical, but mainly using Eclipse (in x11 mode) and Chrome (in Wayland mode)

Repro Steps

1. Add debugConsole=true to .wslconfig (only required to see the odd message, the WARN still appears without this)
2. Start up a WSL prompt and watch the debug console.
3. Before the debug console shows a login prompt, start a window-based application.

Expected Behavior

The application starts and the title bar shows just the application name.

Actual Behavior

The debug console shows a message repeatedly (the odd characters are there), with the time increasing:
A start job is running for Wait for…k to be Configured (6s / no limit)

The window has "WARN: COPY_MODE" in it before the title.

Eventually (around 2 minutes later) the debug console shows:
[FAILED] Failed to start Wait for Network to be Configured.

followed by:

[KSee 'systemctl status systemd-networkd-wait-online.service' for details.
[  OK  ] Reached target Network is Online.

Any windows launched after this work without the warning!
