Offscreen renderingon my IVB is completely broken (often black, or some big
triangles). The rendering crashes after some frames with one of the next
asserts.

Example apitrace dump (captured on llvmpipe):

-------------------------------------------------------

./rasterizer/core/clip.h(431): ASSERT: numEmittedVerts <= 7
    ClipSimd
    Unexpected vertex count from clipper.

-------------------------------------------------------

GetApiState (pDC=0xcc2cb6c0) at rasterizer/core/context.h:411
411        SWR_ASSERT(pDC->pState != nullptr);
