That is a 3D error, i would maybe reinstall the mydmx 3 program.
I will try, but it's a "fresh" installation. I opened this show on another computer with W10 and the effect was the same. (I have W7).
Are all of your graphic drivers up to date? do they all support OpenGL 3.1 or above?
OpenGL 3.1for HD 530 and OpenGL 3.2.1 for Radeon R7 M460.
3D is working. When I run a clean file, this warning does not appear. When I run my show, the warning always appears. Hence my question, what is this file.
according to Dxdiag directX 12, according to the graphic card 9.
