Ubuntu pixelated screen on suspend

I have a ThinkPad x13, 1st Gen laptop with Ubuntu 20.04 and Windows 10 dual boot. It's been about a week and when I suspend the machine, I am getting pixelated screen trying to wake it up.

Below is the description of my machine:

Distribution: Ubuntu 20.04.3 LTS
Kernel Release: 5.13.0-27-generic
CPU Model: AMD Ryzen 5 PRO4650U with Radeon Graphics

I tried a bunch of options from google but it didn't seem to work out. Any help is appreciated.

Your configuration...

Distribution: Ubuntu 20.04.3 LTS
Kernel Release: 5.13.0-27-generic
CPU Model: AMD Ryzen 5 PRO4650U with Radeon Graphics

Note: Booting to an older 5.11.0-46-generic kernel and the computer works fine.

Note: Booting to a Ubuntu Live 21.10 USB and the computer works fine.

dkms status

acpi-call, 1.1.0, 5.10.0-1057-oem, x86_64: installed
acpi-call, 1.1.0, 5.11.0-46-generic, x86_64: installed
acpi-call, 1.1.0, 5.13.0-27-generic, x86_64: installed

To further narrow down where the actual problem is...

• Try booting to a Ubuntu Live 21.10 USB
  • You can boot to a Ubuntu Live 21.10 USB just to test, without installing it
  • In the terminal, type uname -r to see what kernel it's using
• Let's check if you have a current BIOS (ThinkPad x13, 1st Gen)
  • In terminal, type sudo dmidecode -s bios-version. One of the following links pertains to your exact model #...
• Try removing the acpi-call kernel extension
  • sudo dkms remove acpi-call/1.1.0 -k 5.13.0-27-generic
  • sudo update-initramfs -u -k 5.13.0-27-generic
  • reboot to the -27 kernel
• Try updating the Radeon Graphics driver
• Try reinstalling an OEM kernel
  • Check the Lenovo web site downloads for your model

Update #1:

This issue seems to be resolved in kernel 5.13.0-30-generic.
