Same problem and same setting as Goldir. I also have noticed that it happens while chatting. In Fullscreen mode it also completely freezes, meaning I have no chance to shut down anymore [cannot reach the task manager]. In the normal mode everything is fine. Tried everything in the settings cannot find a solution must be some kind of bug. Any solutions?

*edit*

*everything is fine= the freeze can be turned off through task manager, still a forced shutdown but at least my computer is still working
