The sky is "mushing" when I am moving my cursor quickly and one more question

The sky is mushing when I am moving my cursor fast , anybody knows which skyblock will be good?

And to the arcing question - I made a custome music and when it stopping I can’t turn it on again :frowning:
The delay is -1

Probably a leak, but without a screenie or (preferably) a compile log, i couldn’t say for sure.

It’s probably motionblur.

How can I disable it?

And what about the second question

You know this would have been better in the mapping question megathread right?

I would say a leak too, but you said that it happens when you move your cursor fast so I’ll go with motionblur.
