I think the upstream i915 developers might be able to best help you, since the issue still exists in 5.7. I checked and this report looks to be the same problem:

https://gitlab.freedesktop.org/drm/intel/-/issues/347

I'd suggest trying to help the developers debug the problem there.

Looks like intel_idle.max_cstate=4 might be a workaround, of course then you are back to higher power consumption.
