From kernel (tested with up to 5.7) I get the message: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun I added a bug with more details here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872760 but guys from Ubuntu seems not able to help (as it is an upstream bug) !? This happend not in older kernels, but these have the problem not to go in power save states. So I think the fix of that https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1863489 causes this regression. Hope someone can help. For a laptop it is better to have both - standby and power saving. Thank you.

Can I do anything to trigger this and bring that back to focus. It is an really annoying bug and this flickering screen drives me crazy and with "intel_idle.max_cstate=4" runtime is dramatically reduced. From what I read maybe you Chris have biggest knowledge. Can you give me some feedback? Shall I give up hope?
