Virtscreen Appimage Crashes when opening GUI

[IanuReeves]

I am using Virtscreen v0.3.1 on KDE Plasma 5.27.5 if that helps (Archlinux).

Running the app shows the icon on the taskbar as expected, but opening it gave me this error:

I installed all the dependencies required by the Archlinux version in Sourcecode, but Virtscreen still doesn't work.

You will need to add the following to your environment before running virtscreen.

$ export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6

Tested working on Ubuntu 20.4 with both the deb and AppImage.
Your library file libstdc++.so.6 may be located in a different directory.
