I apologize,
I go back to the subject again for advice
and I would like to do some tests.
OBS is able to capture the morphos desktop with the applications that work directly on the screen as a wayfarer and everything that does not require an opening of the "proprietary" screens such as quake demo-scenes, via the hdmi capture card.
In that case OBS still captures the screen natively
but the capture divides the screen into many small squares.
So in theory the capture card works fine otherwise the Morphos desktop would not be captured either.
Nor the proprietary screens, instead it captures those too.

Which Morphos options could I try to see improvements?
for example the frequency of the monitor or different resolutions
any idea is welcome someone had the same problem?

Thanks again.

It would be perfect
