It's probably due to some extension/package which you installed thru GearLock, otherwise I don't find a reason for GearLock being the cause of your game crash....
It improves the speed of moving between options, especially when returning to the previous list. Also, a script such as the one found in the lspeed application can be included, and one of the available options is to activate it if you want:)
damn gearlock is the best tool for those who don't know much about how to change kernel or mesa and some other stuff I love it now going to do work with that video coming ;)
