Linux 5.8.0-50-generic x86_64
Same kernel, same behavior (still assuming it is a kernel issue).
If you like to test different kernel versions there is a script to easily administarte mainline kernels: GitHub - pimlie/ubuntu-mainline-kernel.sh: Bash script for Ubuntu (and derivatives) to easily (un)install kernels from the Ubuntu Kernel PPA. Please read the Warnings section. In addition test if the grub boot menu can be activated by pressing ESC or holding the Shift key on your machine before installing any additional kernel.
