**System Information**
Intel 3770K (OC'd 4.5Ghz)
32GB RAM (8GB dedicated to Blender)
GTX 1070 (Gigabyte with current NVidia Drivers.)
**Blender Version**
Broken: 2.78c Hash:e92f23583 Date:2017-02-24 14:33
Worked: (optional)
**Short description of error**
In Render View or during animation render, blender windows stop refreshing and blacks out, (Multi-Monitor-Setup) see screen shots
{F554357}
{F554366}
(The blackout areas are actually the tool menu, properties, timline and outliner that stop refreshing & will occur randomly between monitors)
**Exact steps for others to reproduce the error**
Based on a (as simple as possible) attached .blend file with minimum amount of steps
<shift+z> Render view, and change view of scene, the window will just start blacking out.
<f12> while rendering, just move the cursor around the screens, and they will blackout and sometimes even distort.
**Additional Problem**
Currently have TdrDelay at 10 seconds, and it is still crashing during renders, even if I reduce the sample rate to 64x64. Not sure what is going on with that. Would be nice to know what the recommended TdrDelay value is, because Windows 10 keeps blocking Blender after it happens more than 3 times.
