Viber Ubuntu Segmentation fault

Latest viber.appImage was not working on Ubuntu 21.10.

The solution was found on https://bugs.launchpad.net/ubuntu/+source/gthumb/+bug/1903569 : The segfault happens in iHD_drv_video.so for many programs.

Segfaults happen with free intel-media-va-driver but not with intel-media-va-driver-non-free.

You can try to replace the free driver like this:

apt install intel-media-va-driver-non-free
