[Jay Taoko (jaytaoko)]

Possibly an issue with support for ext_stencil_two_side on ATI GPUs on older hardware.
A fix has been committed so to use only the regular stencil op (no need for ext_stencil_two_side or ati_separate_stencil support).

[MoLE (moleonthehill)]

will test as soon as the fix filters down to the primary mirrors.
