There are many information (we must wait on answer from developers of CE) in experiment combination of old dtb and actually build for increasing of newer builds without succesfull start at newers kernels of CE22NO:

Maybe is something missing in newers dtbs which was in old dtbs:

Maybe is this issue with some TV if is not good supported higher resolution as 1080p60hz
Jun 10 12:13:01.393309 CoreELEC kernel: [drm] am_meson_crtc_atomic_enable-[0] in: new[2160p60hz], old[1080p60hz], vmode[5-5], uboot[0]
Jun 10 12:13:01.393345 CoreELEC kernel: [drm] am_meson_crtc_atomic_enable-[0]: enable mode 2160p60hz final vmode 0
Only as experiment try change this VOUT mode (with delete of “#”) in config.ini to and use newer dtb: In my case this test not helped me with short time noise.
vout=‘1080p60hz’
