Debian – LLVM error instead of 3D acceleration in Debian stable

I've installed Debian stable (Jessie) on a Acer Notebool (Aspire ES 15).

If I try to start some programs (qtcreator, processing) I see:

LLVM ERROR: Cannot select: intrinsic %llvm.x86.sse41.pblendvb

I think the reason is a not working 3D acceleration.(But I'm not sure)
I already installed the video-intel package with:

apt-get -t jessie-backports install xserver-xorg-video-intel

but this didn't change anything (even after reboot).
