i checked it fine and it works fine when when switched to mode 0
can you please explain what using this mode instead of default one means in practice?
It
appears that some drivers say certain features are supported by the
hardware even if the hardware does not. In this case the feature
is rectangle texture support. 'mode 0' tells pix_texture to use
2D textures. The default is 2D but GEM checks for support for
rectangle textures and uses those if found.
