Restart WSL to re-enable WSLg display for running the GUI

[anopheles]

The app was ported from Python 2 + PyQt4 to Python 3 + PyQt5 and verified to run correctly headless (offscreen Qt platform + screenshot of the rendered Lobby window). It's not yet been seen running on an actual display in this WSL environment.

Blocker

$DISPLAY is empty and WSLg isn't wired up in the current WSL session — no working X11/Wayland socket, and /mnt/wslg/run/user/1000 is present but inaccessible/empty. Running python3 instantsoupmain.pyw fails with:

qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.

Fix (do this on the Windows side, not inside WSL)

1. In PowerShell/CMD on Windows: wsl --shutdown
2. Reopen the WSL terminal.
3. Verify echo $DISPLAY shows something like :0.
4. Run:

   cd ~/dev/InstantSOUP/src && python3 instantsoupmain.pyw
   

If WSLg still doesn't come up after the restart (e.g. older Windows without WSLg support), fall back to installing an X server on Windows (VcXsrv or X410), launching it, and setting DISPLAY manually, e.g.:

export DISPLAY=$(ip route show default | awk '{print $3}'):0

Also needed once (already done in this session, but noting for a fresh machine)

sudo apt-get install -y libxcb-icccm4 libxcb-image0 libxcb-keysyms1 libxcb-render-util0 libxcb-xinerama0 libxkbcommon-x11-0
pip install PyQt5 "construct==2.5.3"

Krass, du programmierst daran noch? Einfach Hobby oder für irgendwas notwendig? 🙂
