I have updated my Ubuntu 20.04 to 22.04 and I realize that my Viber has a little bug. When I try to view some video in group or chat it looks like transparent. See the screenshot.

Ubuntu-restricted-extras installed, the google says nothing about this trouble. Do you have any suggestions what should I do? Thanks!

I solved this trouble. I removed totally viber through apt and reinstall it with flatpak

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

To install it I used the command:

flatpak install flathub com.viber.Viber

To run:

flatpak run com.viber.Viber

The trouble disappeared.
