Hi all,
after the matrixoutput of gridshape I get back Z and use slab to modify him, and I use mesh. I have of to forget something!

the same here. Max crashes when going to fullscreen

Thanks for the report. I am able to reproduce, and we will look at fixing this. It seems to be somehow related to floating point readback. If I force the input slab be char data, it works without crashing or pbuffer errors (though obviously there is a problem with 8bit resolution).

Here's my modified patch which worked for me.

Another solution in the meantime is to use [; jitter glreadback fbo] Place in a message box and loadbang it on patcher load.

ok, thanks  Joshua.
your modified patch work for me too.
And glreadback fbo  ok.

FWIW, this is fixed in the forthcoming 5.1.5. Thanks for your help our finding and squashing some long standing bugs related to floating point textures.
