you're not the only one, I keep getting this too just before my viewer crashed (if I use firestorm) the normal SL viewer crashes instantly
the only "fix" I can find is to use an old firestorm version (4.6.9(42974))
My specs are
CPU: i7 975 extreme edition
GPU: Gtx 780
Ram: 16 GB
OS: Windows 10 Pro 64bit
my pc doesn't overheat, and I've tried formatting my pc without it fixing it
