I get this error randomly on every project(template projects both blueprint and c++). It just pops out randomly.

Try pasting the whole callstack, but I am afraid this might be again a problem.

You are very right, i should have tested it with intelHD before. I didn’t encounter the same problem with intelHD.

Please, don’t say me this, yesterday i installed optimus for try work with Unreal Engine, but, i don’t test it yet.
If i don’t use optirun in the editor launch command i wont have problems, right?
