Inspiron 16 Plus Intel GPU Problems on Ubuntu (Screen Tearing, etc...)

I recently purchased a new Dell Inspiron 16 Plus (Intel i7 11800H, RTX 3060) and I want to use Ubuntu 20.04 in dual boot.

There were issues with both gpus from the start, what helped so far to mitigate the problems was adding

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_psr=0"

to /etc/default/grub (found in this forum) and disabling secure boot. The NVIDIA gpu works fine now, but there is screen tearing (see photo) when I use the Intel gpu, for example when I drag a window across the screen. Youtube videos in 3k resolution also have lags and do not run completely smoothly. I noticed that this problem only occurs with fractional scaling (e.g. 125% or 150%).

In Ubuntu forums it is often suggested to add

Section "Device"
    Identifier "Intel Graphics"
    Driver "i915"
    Option "TearFree"    "true"
EndSection

to /etc/X11/xorg.conf.d/20-intel.conf, but this results in all sorts of graphic artefacts and made my system unstable.

Did anyone experience similar issues and managed to fix them?

I also tried to add the following extension to /etc/X11/xorg.conf.d/20-intel.conf:

Section "Module"
    Load "dri3"
EndSection

Section "Device"
    Identifier  "Intel Graphics"
    Driver      "intel"
    Option      "DRI"   "3"
EndSection

Which made it even worse (see photo)

I am also facing the same kind of issue, where screen flicking issue is observed on both intel and nvidia graphics running ubuntu 20.04 focal. Also when we boot first time screen goes to totally black color no cursor after unencryption hard drive message. I had to hard power down the laptop 2 to 3 times always, and in 4th or 5th attempt I am getting ubuntu login screen. So this is really disappointing. Do you know if Dell has fix for thisgraphics drivers, why they are only creating hardware for windows lovers and not linux lovers?
