[jitter] Bug report: jit.gl.slab not able to change context

Coming in late on this one again, as I have kept working on slab-based 
patches and seen some more patterns that might be worth reporting.

I am not able to find any consistent steps that will produce the errors. 
However, when the error appears, it starts immediately as soon as I 
start rendering to a new context (e.g. first time after opening the 
patch and starting to bang jit.gl.render et al.). And I have found a 
simple workaround that seems to consistently solve the problem without 
having to close the patch or restart Max: If I use a rect message to 
jit.window to resize/move it somewhere else, and then move it back where 
I want it to be, the errors are gone and rendering and slabs work as 
supposed to. I don't know if this might provide some additional clues to 
tracking down what causes it.

Best,
Trond
