Hi, @eldendo and welcome

I had the same issue and found a solution: disable GPU passthrough (GPU passthrough was introduced into the kernel at the exact time the irregular "on/off-flashing" began.)

if you are up to editing the config of the bootloader this might help:
open a terminal and type:

sudo pluma /etc/default/grub

replace this line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

with this

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_iommu=igfx_off"

save, close and run grub updater

sudo update-grub

and reboot

More things to try in this thread (read whole thread first):
