System crash/reboot on Steam dmg shader

I haven't taken any actions, because it happens very rarely. It was mostly to alert the QA team on your end. It seems that the VFX changes over time, because it doesn't happen right at the start, but when  you take significant amount of dmg from the steam or when the effect reaches a certain level. I am very positive it's something to do with the particular shader used, so it might be related to the set of instructions, especially if it's a manually written shader. Thanks!
