CoreELEC 19.4-Matrix_rc2 Discussion

Hi support,
I have an issue that make a black screen when start and/or stop video, mainly UHD.
Other users have the same see here, this is NOT solved, only a workaround is to change the HDMI input in the AVR and go back to CoreElec player.
In the test I played jellyfish 180mbps, had the black screen then “no input” from the TV. At the end it came back fine to the menu. You will find it due to the same repeated log lines. Note I tried a static disp_cap but nothing better.
Find the log: hastebin
Let me know if you need more info/tests
Thanks
