Editor crashes in Game Mode on maximized view

Tried pretty much every Unity build up to latests 2017.3. Brand new project, nothing but camera and directional light. works fine in default, minimized mode. Once I click play button with Maximize on Play enabled game starts running but after clicking on Play again to stop game mode editor crushes.

I am running Ubuntu Ubuntu 16.04 LTS.

Any pointers how to solve this problem?
