How curious! I'm having the same issue resuming from sleep on an Ivy Bridge machine (iHD 4000).
I just upgraded from a Geforce GTX TITAN to a Radeon R9 290X, and I was blaming the AMD driver out of habit, but upon reflection, it may be the new Intel driver. I did a fresh install after I removed the Geforce and before I installed the Radeon (not dealing with those nightmarish driver conflicts ever again) and in the process downloaded the latest Intel driver. I was using an older driver version before.
I already submitted a bug report to AMD; wish Intel had a 'driver feedback' page like AMD does.
