However, there seem to be no Direct 3D acceleration for compositing in this configuration.

Setting webgl.force-enabled and layers.acceleration.force-enabled to true also makes no difference. Reproducible: Always
Direct3D 9 composition is not enabled because of the Maximum Texture size being 2048x2048 on the 915GM if I'm not mistaking. We require 4096x4096, i.e. it's not blocked for any particular reason, but it's also not supported.
