Beta 7.95.2 on PI 3 green LED (SD-Card Activity) malfunction

Hello dear community, I'm quiet new to the RPI and LibreElec/Kodi, however, I have a problem with the latest release, running it on my 'naked' PI 3.

When I power on the PI, in the past three months (until release 7.95.1) , the following happened:
- red led went on
- green led was flashing
- Display went on, displaying the "startup-screens" (LibreElec-Version and Krypton-Logo)
- Kodi was ready -> red led was constantly on, green led was flashing frequently

After the update on 7.95.2 the following happens:
- red led goes on
- green led flashes exactly once
- display is showing a multi-coloured-square for a few seconds
- then booting starts as used , displaying the "startup-screens" (LibreElec-Version and Krypton-Logo)
- Kodi is ready
however the green activity LED is completely off and only turns on (flashing some times) when I shutdown the system.
Kodi seems to be working as usual.

I removed all USB-Devices, the LAN cable > same symptoms
I did reset the system to default values > same symptoms
I did not turn on the debug log, but there was nothing than the successful start event in the regular event log.
I did make a backup and then formatted the sd-card writing the image of 7.95.1 > now the PI works as usual
I did make a new image with 7.95.2 > the symptoms (no green-led activity and displaying the colored square) start to show up from the first start (before the setup routine starts)

What's wrong with this version and how may I contribute to fix the problem?

I could be mistaken but the green LED is disabled intentionally on release and release candidate builds.

Hmmm .... but all explanations I find for the colored-square say, that something with the kernel is messes up and usually the PI is not booting anymore, and freezes with this display. I would not mind that the green activity LED does not flash during normal operation, but in combination with the square ... I assume that something is not as it should be

The multi-coloured-square at boot is a GPU test.

The coloured square appears after firmware has loaded and remains until kernel replaces it.
If it stays up it means the kernel failed to start.

Most common cause is updating a Pi2 with Pi1 image (or vice versa).
But sdcard corruption or an interrupted update could also cause it.

A reinstall may be the simplest option.

Hmmm: As I formatted the SD card several times, and successfully reinstalled different versions I do assume that this is not the problem. It also does not stay up, it's just visible for a second or so - but it has not been visible in other versions.
