mDrawGui with Ubuntu

[Buitani]

Started mDrawGui with
sudo python3 mDraw.py

When I want to open mDrawGui it looks fine, but in the terminal I got this message:

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'

mDrawGui does not work properly. I cant load files.

Any suggestions what I can do?
