I can confirm the issue. Having the same problem on a LENOVO ThinkPad W530 with BIOS version 2.60 and NVIDIA Quadro K1000M using the NVIDIA Quadro 341.21 driver and ESET NOD32 Antivirus 8.0.304.0. Reverting to a snapshot has fixed the issue for me for now. Please inform me when a fix or workaround is available.
