Hi, it sounds like the GLSL compiler is barfing on something in one of the shaders you are using. I don't personally have access to a raspberry pi 3 at the moment but we'd of course like Qt 3D to work on such devices too. Can you file a JIRA with instructions on how to reproduce with a small example please? I'll see if anybody here has a rasp-pi 3 to test on so that we can fix this.
