Same issue here wemo.
HP ZBook 15u G2:
- Intel Core i7-5600U 2.60GHz
- 16.0 GB RAM
- AMD FirePro M4170 (driver version 15.201.1301.0)
- Intel HD Graphics 5500 (driver version 20.19.15.4300)
- Windows 10 Pro, 64-bit, Version 1607, OS Build 14393.447
- Dell D3100 (36M9K, Sept 2015)
- 3 external Dell monitors + laptop display, total 4 screens
All worked great prior to the latest major Windows update. Still works, but performance is degraded, text/elements sometimes won't draw on the screens until I move the affected window(s) around, etc. Haven't tried gaming as this is a work setup, but I suspect performance would be poor.
I'm currently trying the R8.1 Alpha driver (
