On OpenGL ES 3.0, some drivers are veeeery slow linking a program which includes transform feedback - and such program is needed to apply vertex effects to meshes - which is needed to round corners of puzzle cubits.
Thus on 3.0 we switch off rounding corners of the meshes in the Creator mode, otherwise we'd need to wait about 24 seconds for the screen to appear!
