Actually there is something in the logs that I missed the first time:

[ 69.108687] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun

Do you know whether earlier 5.4 kernels in focal also had this same issue? If not, do you know the last version you used which did not flicker after suspend?
