It took me some time to spot it, but there is something like a grid on the frames before the lineup of RWBY.

Provided that the water colour effect has actually a meaning, a combat simulator is definitely a good explanation.

But the effect also occurred in scenes where it makes no sense as a side effect of virtual reality, like Pyrrha appearing behind Ozpin.
