Repro Steps

Hello,
I try to launch GUI application (qemu) from remote host.

1. Locally (wsl2) I launch: ssh -X my_remote.host
2. launch qemu with requred flags

Got error:

X11 connection rejected because of wrong authentication.
Could not initialize SDL(No available video device) - exiting

It looks like wsl2 does not set up XAUTHORITY environment variable and remote client is unable to authenticate gui session.

Simple application like xsnow, xeyes are working sucessfully.

on wsl2, xauth package is installed

Expected Behavior

qemu is launched with GUI session

Actual Behavior

qemu fails with error:

X11 connection rejected because of wrong authentication.
Could not initialize SDL(No available video device) - exiting
