Insert a slab in the chain

Dg's icon

Hi,

I'm trying to get better performances with my patch.
Each time I insert a new [jit.gl.slab] I get the traditionnal:

jit.gl.pbuffer: error binding texture: GL Error: Invalid operation
jit.gl.texture: unable to create texture!

(render stopped)

... and then need to relaunch the patch.
Is there something to reset before to insert a slab?

Thanks.
