Witcher 2 - GLSL enabled - 01

As summary, during gameplay screen is white and/or coloured in a glitchy way.
Screenshots will be uploaded to show this more clearly. The main error seems to
be this:

err:d3d_shader:shader_glsl_select >>>>>>>>>>>>>>>>> GL_INVALID_OPERATION
(0x502) from glUseProgramObjectARB @
/var/tmp/portage/app-emulation/wine-1.3.20/work/wine-1.3.20/dlls/wined3d/glsl_shader.c
/ 4625

Additionally, setting "UseGLSL = disabled" works around the issue.
