"csgo_linux64" is not responding
I have encountered this problem after CS:GO updated to "Danger Zone". Before that everything worked fine.
Now it says: "csgo_linux64" is not responding. You may choose to wait a short while for it to continue or force the application to quit entirely.
My system: Ubuntu 18.04.1 LTS 64-bit; Mesa 18.2.2
Solution 1:
When you get options. Force Quit and Wait, press on Wait. Sometimes the dialog box opens again with same options, press wait again
