I'm using Intel internal graphics for playing factorio on Linux mint. Most time I can play fine, no fps drops etc.
BUT
When any popup appears - It could be steam friend, Telegram messenger or even steam achievement - my game freezes in 99% cases and only kill -9 helps.

After alt+tab game feeezed, can't move or quit to menu - nothing works

Logs attached. This is not save related problem, it could happen on any save but save is provided
UPD 1: After many tests - it could happen in menu too but with less chances
UPD 2. Steam 0.15.x (currently 0.15.31)
