3) Play Civilization VI on Ubuntu via Steam expect to see smooth
rendering with clear textures. This was the case with 4.8.0-39 kernel.
4) With 4.8.0-41 kernel rendering does not work as expected. Some
corrupt/zeroed textures appear.
After installing new package version and reboot everything works until
machine is power cycled. After machine is power cycled at lest once
issue reproduce permanently. Reverting kernel with power cycle fixes
issue.
