Comment 133 for bug 1321623

I've been able to replicate this bug in two different PCs and two different Mint distros: Xfce 17.3 and KDE 18.1 but always booting from a Live USB. After installing the distro to a hard disk the bug didn't appear anymore. For those who have tried to replicate this bug I think I've found what causes it. The system freeze happens a random time after opening Firefox browser. Disabling hardware acceleration seems to solve the freeze. I'd appreciate more users affected by this bug replicate these steps and confirm if they solve the problem for them and be sure Firefox hardware acc. is the culprit.
