Hi Roy,
You're right. This problem is caused by failing to
request cStencilBits in OGL getPixelFormat. Therefore
in some case sthe driver may return a pixel format without
stencil buffer support which is required by current
DecalGroup implementation.
In v1.3 it is fixed by explicitly request one and
fail back if getPixelFormat fail. As a result
the memory requirement is higher and we see in
case of ATI laptop running 1600x1280 resolution
will cause the driver fall back to emulation
mode if window resize bigger than certain
dimension. This does not happen in v1.2.1.
Thanks.
