Yes this does seem to be a driver crash, and generally there isn’t anything that can be done engine-side to resolve that, but we have had a few users say they experience driver problems after they updated to 4.11, so we are following up. We haven’t been able to reproduce any issue internally, so we’d appreciate if you could share some additional information. What is your Operating System, and what graphics card are you using?
Also, is there any reproduction case that causes a driver crash 100% of the time for you?
That’s ok - to be honest it’s been totally random, but mainly any window thats rendering something, like a Blueprint editor viewport for example. I’ve uninstalled my drivers, performed a clean with CCleaner and re-installed… so far so good.
