This is beyond the control of compiz/beryl as the GLX_EXT_texture_from_pixmap spec mandates that the texture target be strictly derived from the pixmaps dimensions. Any possible workaround would probably have to be in the X server. Note that the lack of NPOT support means that up to almost 4 times as much texture memory is required, and the machines that lack NPOT support will tend not to have plenty of resources to begin with, so I'm afraid this is just never gonna really fly on that kind of hardware. -- Earthling Michel Dänzer | http://tungstengraphics.com Libre software enthusiast | Debian, X and DRI developer
