Ok, I'll check it out than when the next update is out. As you said you haven't seen this on any other of your computers, just to let you know that I'm on my custom build hackintosh, so it's not really mac, even though I'm on OSX. And sometimes it's giving me all sorts of strange problems, so I don't know if this could have something to do?
As I already had similar problem on my laptop: https://vuo.org/node/2209
It might be something similar - something GPU related, but this is happening on my desktop. I have 2 nVidias 1070 Ti.(no Intel iris.) This time no 3d nodes involved, I tried on very simple composition jus to see.It doesnt really affect the funcionality of Vuo though.
After updating to Vuo 2.0 my vuo files do not load in Vdmx. I have replaced the old deprecated 'Render scene to image' nodes to version2.0 as recommended. Cleared the Vuo cache in Vdmx.
As my files contain many 3d object nodes (that were already giving me problems in the past), I made a simplest file just rendering a layer just to see, but still get the same message 'There was a problem loading composition'.
When I try to trigger vuo 1.2.8 files (with old deprecated nodes) Vdmx loads them fine. Only the Vuo 2.0 are affected.
