Using vMix 15.0.0.88 on Windows10. Almost everything works great. But, am getting some blue-screen errors in windows sporadically (but consistently) across our various computers. Having some trouble determining steps to reproduce this. Here's what I know:

1. In the directory configured to store the recording, we see logfiles, which contain this entry:

========================================
15.0.0.88 - Present.Main - 8/22/2015 2:30:57 PM
========================================
SlimDX.Direct3D9.Direct3D9Exception: D3DERR_DEVICELOST: Device lost (-2005530520)
at SlimDX.Result.Throw[T](Object dataKey, Object dataValue)
at SlimDX.Result.Record[T](Int32 hr, Boolean failed, Object dataKey, Object dataValue)
at SlimDX.Result.Record[T](Int32 hr, Object dataKey, Object dataValue)
at SlimDX.Direct3D9.SwapChain.Present(Present flags, Rectangle sourceRectangle, Rectangle destinationRectangle, IntPtr windowOverride)
at dq.zs(SwapChain a, vzzzzy a)


2. According to Microsoft, this error can cause video memory to be lost (https://msdn.microsoft.com/en-us/library/windows/desktop/bb174714(v=vs.85).aspx

3. PC reboots (presumably BSOD) within a few seconds of the DEDERR_DEVICELOST log entry. Nothing else in windows event log before that time looks suspicious (at least to me).

4. System is Intel Core i5-4210U CPU. Intel HD Graphics 4400 (driver 10.18.15.4256)

Seeing that changes to power are mentioned in the Microsoft article, we've done our best to make the computer turn off, go to sleep, run in maximized power plans, run on minimized power plans, etc. and can't seem to find the set of factors that make this repeatable, but it definitely happens on several identically configured computers at some point during almost any 2-hour period.

Any help would be GREATLY appreciated!
