WinPixGpuCapturer.dll crash in viewer when resizing render target.

I can reproduce this reliably just by opening something like DeferredRendererPBR/main.gg and repeatedly changing the RenderSize variable. Within a dozen attempts, I hit a fatal crash. Running with GBV, the debugger output:

I've hit that before but never with GBV. Thanks for that info, that ought to help track it down!
