I’ve a new 8 core macpro with radeon card and blackmagic extreme, everything is working properly, except simulaneous playback of the canvas/ viewer and the external monitor.
So when playback_all_frames is chosen I see my video playing on the external monitor but not on the canvas nor the viewer when I stop playback the canvas/viewer updates to the latest frame. It happens with xdcamEx , proresHD and pal footage.
When external playback is OFF, the canvas / playback is normal.
I’ ve never seen this before on other systems .
Help is appreciated
