Fuzzy graphics after upgrading to Ubuntu 20.04

I have recently upgraded Ubuntu 19.10 to latest LTS Ubuntu 20.04. After updating, I get serious artifacts on my screen. Every time I reboot (or log-in), my screen is fuzzy or scrambled (picture attached):

This is temporary. The fuzzy screen goes away when I change the background. But it reappears the moment I reboot or log back in.

I have Intel HD Graphics 520 (Skylake GT2).

The output of lspci -nn |grep -E 'VGA|Display' is:

00:02.0 VGA compatible controller [0300]: Intel Corporation Skylake GT2 [HD Graphics 520] [8086:1916] (rev 07)

Update:

On enabling Wayland in Ubuntu 20.04 and logging in to, these artifacts are however cured.

This is okay for now, but I am not sure about Wayland as I have not yet used it before.

Is there a way to correct the graphic issue with normal Ubuntu startup?

I solved my fuzzy graphics issue which is related to Intel Drivers. A bug is also reported on Intel driver artifacts. Following the answer provided here this command line solved the issue:

sudo apt purge xserver-xorg-video-intel

Reboot and everything is back being normal.
