This happens to me too with intel graphics, although not on every suspend / resume cycle. I'll test the mainline kernel and see if that fixes the issue. My machine has had issues in the past with SNA acceleration, this may be another case where falling back to UXA fixes it.

As it happens not at each suspend resume I find it hard to diagnose what is going wrong. next time I will launch more apps to see wich ones are affected.
