Summary0001750: Random crash in complex scenes
DescriptionNested ItemsControl (StackPanel, not virtualized, vertical then horizontal), rendering a total of 200 times 45 buttons. Depending on the complexity of the templates, actual numbers may need to be increased.

Expected behavior:
It's slow to compute the layout.

Actual behavior:
It's slow to compute the layout, followed by various callstacks ending up with a write access violation in these top 3 frames:

     vcruntime140.dll!memcpy() Line 243
     Noesis.dll!Noesis::DragDrop::GetClassType() + 4657 bytes

The cause is not entirely clear, but it appears to happen whenever scene complexity approaches ~30k allocations.
The system is still far from going out-of-memory (just 200MB used reported by Noesis itself), and it doesn't appear to be dependent on effective render resolution either.

Attached is a minidump for one of the crahes.
TagsNo tags attached.

Thanks for this, the dump contains all the information we need. There is an internal overflow in our command queue.
