looks like as if the driver falls back to GDI renderer .. hmm.

pretty much a driver bug, and arbcontext should work.

Nope, that is an issue w/ Intel driver using pbuffer and failing.

sadly not, but then we are using a fairly new AMD driver
on our windows test machines.

Is that a current driver version ? Looks like.

'AMD Radeon E6760' refers to which GPU ?

I will setup another test machine w/ latest AMD driver,
since our remote test machine w/ AMD Windows works.

Hope it's not GPU related (as in code path per GPU type in driver).
