Amlogic-NO discussion

I have latest nightly build running on Homatics Box R 4K Plus and noticed that kodi.bin uses almost 100% of CPU time when HDMI is plugged off (AV receiver turned off). Once I plug HDMI back, kodi’s usage is at few percent. The box is supposed to be idle at that time.

I didn’t have this problem with official 21.3-Omega NG build.

Is this known issue? Anything I can do about it?
