Recently i have had the issue of strange artifacts after sleep mode. I ve updated my NVIDIA driver as stated in Strange artifacts along window borders after waking computer from sleep mode and all seem to work out.

I no longer have the issues around the windows but Viber seems to still be affected. The profile pictures and pics inside a chat are still acting weird!

Is there any more i can do or it's just the bug not fully fixed?

Please restart compiz with:

compiz --replace

It worked for me. If it does not work, install the latest Nvidia driver "nvidia-381" which fixes the issue, you may not find it within standard repositories so please add it from a PPA :

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
sudo apt purge nvidia*

sudo apt install nvidia-381

After this please reboot your computer and check if problem is gone.

I hope it helps.
