I have this and this problem, so it’s turned out that 5.5.3f1 was better for me than 5.6.0f3, but there is still problem. What version would you recommend to try ?
Did you file any bug reports regarding your issues?
Done. About both.
Skybox problem solved.
@OP, Unity’s struggling a lot with outputting stable versions of the engine. Generally, a .0 version often breaks things (so 5.5.0, 5.6.0, etc). If you want a more stable version, go with a .1 or .2, as those generally don’t have new features, just a bunch of fixes for everything that got broken in .0.
