Oh well. Intel drivers on Windows are always full of surprises :/ For the record, I'm not getting such issue on Intel Mesa drivers on Linux.

What's the full engine log (including extensions and workaround used)? Maybe disabling some of these could make it work.

I was plowing through all the bugs related to Intel Windows drivers and this was one of them, cube maps in particular were extremely broken. I managed to reproduce and two new workarounds are in place since mosra/magnum@580a3c5 and mosra/magnum@f9c6dea, which are fixing this issue. (Apart from these, there's 6 other workarounds "fixing" other Intel bugs.)
