Frame.setlocation(x,y)

[x3sp3d3s]

Hi, I'm here again! Now I have another problem, we use :
size(client.getLWidth(), client.getLHeight(), SMT.RENDERER);
and our sketch starts outside of our screen, but we use too: Frame.setLocation(0,0).
The problem is that, when we run the project for the first time, it doesn't work :
OpenGL error 1282 at bot beginDraw(): invalid operation
OpenGL error 1286 at bot beginDraw(): invalid framebuffer operation
OpenGL error 1286 at top endDraw(): invalid framebuffer operation
OpenGL error 1286 at bot endDraw(): invalid framebuffer operation

In internet I read that's a problem between SMT.RENDERER and frame.setLocation. Can anybody help me??
Thx
