PSA for any fellow Linux CS players out there: the June 20 update to CSGO made the game crash on every launch for me until I disabled the Steam overlay. Not sure exactly what the cause was, but I suspect something with CSGO doesn't play nice with the redesigned Steam overlay.
Thanks for the info, I'll try this out. My experience is slightly different, in that it would load fine the first time, but then crash on launch every subsequent time until I rebooted my computer. I've also occasionally been getting crashes entering text in Yprac maps.
