Comment # 7 on bug 94671 from Nicolai H�hnle

Hi Jan! First, please try this patch which fixes a similar bug:
https://patchwork.freedesktop.org/patch/78118/

If that doesn't fix the problem: I'd appreciate if you could upload the
apitrace somewhere (Dropbox, Google Drive, etc.). A diff is not going to be
useful.

But first, try if the problem is already fixed with the patch above :)
