The exact error message might help.
Hi Jim, Yaobing, here you go:
'The display for this zone is owned by a different window'
The issue went away for awhile, today it's back without any specific reason.
Tried starting a Live TV channel, after approx 30 the video isn't shown anylonger. At the same time the channel's logo gets showed and the above message appears at the same location where the OSD normally is.
Audio is still present.
Leaving Theater View for Standard View brings the video back.
Restarting MC solved the issue, at least for the moment.
I'm on .47, Windows 11 and using the latest Nvidia driver.
In case you want me to test something let me know.
Cheers.
