The issue still exists. After updating (10.0.3) and rebooting, I have no image. No signal. I have to go back to version 10.0.0 again.
Samsung UE55M5572, RPi4B 4GB, HDMI... (first on the left), normal case.
same here, LG tv, have to revert back to 10.0.0 again.
Just wanted to post here to mention that i have the exact same issue, not sure if i can help with anything or if there is a solution ?
I thought i would register here to post what i have found by reading all the way to the end of the internet 
from what i found, this is an issue when scummvm is compiled directly on the raspberry pi from the Repo (again, im a newb, my wording might be wrong), so i found one that was manually compiled on a computer, i have attached it here, you can manually install this version on your PI and it should work (it works for me)
i can host this for now on my private server but if someone could host it somewhere public that would be appreciated :
