Can you please check if bug #1526658 isn't your issue? Check which mir-platform-* packages you have installed. Thanks!

@Michal Sawicz, as far as I understand the problem in bug #1526658, my problem is not due to wrong/old packages.

I have some updates for mir-client-platform-mesa4, mir-graphics-drivers-desktop, mir-platform-graphics-mesa-kms7, mir-platform-graphics-mesa-x7, mir-platform-input-evdev5 and unity8. I am going to update system and try to see if these updates fiz the issue.

I updated system but the bug still exists. Additionally, I can no upload crash report due to the bug #1439687. I am trying to debug unity8 but I could not do it so far.
