empty window when AppImage is run remotely via X-tunnel

[cdruee]

Executing MQTT-Explorer-0.4.0-beta1.AppImage via ssh -X just opens an empty window. The same thin has been for signal-desktop, which is an electron application, too.
It is a bug of the special chromium version bundled: https://bugs.chromium.org/p/chromium/issues/detail?id=1048186#c8

As a workaround, calling
QT_X11_NO_MITSHM=1 _X11_NO_MITSHM=1 _MITSHM=0 MQTT-Explorer-0.4.0-beta1.AppImage
works, but please do us a favour and bundle the Appimage with a repaired chromium.

Thanks a lot!
