Description
When the graphics is not present, the following logs are observed in the terminal
```

Otherwise, either the object is completely black, or it is placed in some random location.

Research direction
No source files or tests are named. Start by reproducing scene loading with graphics absent and inspect framebuffer state around the logged glClear, glDrawElements, and glBlitFramebuffer calls; done means scenes render correctly without black or randomly placed artefacts and without GL_INVALID_FRAMEBUFFER_OPERATION errors.
