Hi, I just installed ML on EOS M and I am completely new to it. It was the experimental version crop_rec_4k_mlv_snd_raw_only_2022Aug04.EOSM202.zip. I did it in a hope of having 5k anamorphic frtp continuous, which is the only video mode which interests me at the moment (low light loss on the sensor and no aliasing). Before installing, I chose "clear camera settings".
So, in this fresh install, firstly I have set the mode:

Then the hacks:

As suggested in the mode description, UI kill ON. I have also set basic things as suggested in "display warnings", like the manual mode.
Then I got this strange preview:

It is not quite static, the colored fields move slowly.
When resetting the camera or pressing the lens button in the bottom right corner, the preview switches to this:

The top part shows now a clear preview (dark in the screenshot as there was actually no light) and the bottom part flickers fast random pattern/black.
I never got the nice preview from Zeek's video
i.e. recording levels on the bottom. Additionally, when pressing the Menu button in ML menus, the camera sometimes bricks. After power cycling there is only the green led blinking. Removing the battery helps returning to ML.
I wonder if there are some settings, not shows in Zeek's video, which allow to obtain his results and stabilize ML?
Firmware 2.0.2, 512GB 120MB/s sd card. LM installed via "update firmware". Under Debug, there is something like this:

I do not know if it is a problem or if it was like that from the beginning or only after a number of freezes/debrickings.
