Unhandled exception when resizing DirectX12 demo window.

[digimap2000]

Running the DirectX12 example code unmodified. When resizing the example window I get an unhandled exception after about 3 seconds of dragging the window. Call stack is....

Correction, I had added some fonts. Removed those, still crashing. DirectX 11 test works fine.

[PathogenDavid]

I can't repro this. Judging by the stack trace, this is coming from the DirectX debug layer. There should be a message in Visual Studio's output window with details.

Closing as supposedly fixed by #8961. But since this is old and hard to repro for me I guess we can only assume it is fixed and if another issue arise we'll find out through new reports.
