Just updated to 6.4.011 and Zgemma H7C won't play 4k 60Hz video properly.
It plays with thin horizontal lines drifting up the screen.
Then when you stop the video, the screen goes black with vertical bands of colour, made up of same colour in each band, drifting across the screen.
The screen then goes black and the box locks up. Need to power down with on/off button.
Checked with 6.4.010 in slot 2, and same video plays perfectly ok.
Have exact same settings in both vix versions.
