Running the 1.13.1-x64 AppImage on Kubuntu 20. When I attempt to flash a local `.iso` file to a USB stick, I get an OS request to run `/bin/bash` as superuser. This prompt goes into the background and by default ended up behind the Etcher window. I didn’t see it for a good while and kept waiting for the flashing to start.

Maybe it’s worth warning the user about this, or asking them to run etcher with `sudo`, as Unetbootin does.

Thanks for the feedback, it is probably something appimage specific, we will investigate this.  
Do you have some appimage integration on you system or you ran it as is?
