I like to know the source of your information. Perhaps I can find some more hints or other possible options to use.

Best source is internet search ...
Some good source is maybe:
https://wiki.archlinux.org/index.php/Intel_graphics
or
https://bbs.archlinux.org/search.php?se … 1922492135

But not all things from arch are applicable on different operating system

Best regards...

I am pretty sure its not a hardware or BIOS issue. Its a driver or a set of configurations which makes the Intel iGPU fuzzy

Hi, you can try create file 20-intel.conf
with content

Section "Device"
   Identifier  "intel Graphics"
   Driver  "intel"
   Option  "TearFree" "true"
   Option  "AccelMethod" "uxa"
EndSection

Create directory in /etc/X11 named xorg.conf.d

And copy as root file 20-intel.conf
to
/etc/X11/xorg.conf.d

restart

After that installation I got error messages from nvidia-persistenced both in Synaptic and the console during installation of any package:
nvidia-persistenced failed to initialize. Check syslog for more details

I've got the same message during nvidia-persistenced installation process.
This can be avoided, you can run command in terminal :

sudo dpkg --configure nvidia-persistenced

If nvidia-persistenced runs, check in terminal :

ps aux | grep -i nvidia-persistenced

Possible answer looks like

nvpd      1632  0.0  0.0   4672  1596 ?        Ss   21:03   0:00 /usr/bin/nvidia-persistenced --user nvpd
