yes, that's what I'd expect too. If the texture are 0x0 it seems the
size of the viewport is not set correctly.
I just noticed that the Viewport left,right,top,bottom fields don't have
default values and committed a patch to fix that.
Are you setting the viewport size explicitly?

That would mean there is a bug in the GLObject handling. Possible, but
given that your other textures in the scene are correctly recreated on
the new context (right?) I'd think that is probably not the issue here.

In general yes, just a matter of finding the bug that prevents it from
working in this particular case ;) Thanks for being patient.
