jit.gl.slab bug
The patch is too big and too complex to put it all here but I found a bug with a jit.gl.slab @file.rota.jxs object.
I say it must be a bug because whenever I move the object a little bit more to the right on the patch window, it starts outputting white instead of the normal footage.
Weird!!
I am using Max 6.1.3 on OSX.
Max Patch
Copy patch and select New From Clipboard in Max.
This is what I am moving around
we're gonna need to see a complete patch and more explicit steps to reproduce, to be any help diagnosing this.
don't post your whole patch, but just enough to demonstrate the problem.
