QStandardPaths: runtime directory '/mnt/wslg/runtime-dir' is not owned by UID 0 #27694

Is there an existing issue for this?

• I have searched the existing issues

Current behaviour

There is the message after launching bitcoin-qt in Windows Subsystem for Linux:

# /usr/local/bin/b25/bitcoin-qt
QStandardPaths: runtime directory '/mnt/wslg/runtime-dir' is not owned by UID 0, but a directory permissions 0700 owned by UID 1000 GID 1000

Bitcoin-qt is launched successfully and runs smoothly despite the message.

Expected behaviour

There isn't the unexpected message: "QStandardPaths: runtime directory '/mnt/wslg/runtime-dir' is not owned by UID 0, but a directory permissions 0700 owned by UID 1000 GID 1000".

Steps to reproduce

Launch bitcoin-qt from a command line.
