[D3D12] Constant Buffer overflow

Every few maps, during a juiced ritual encounter (4x Glacier boss vessels in the map device), the whole screen starts to flicker, and when that happens, about 50% of the time the client will crash. The log file indicates a DirectX 12-related buffer overflow.

Bug number generated in the same map after the crash: 359,252,003

It just happened again in the same map, next ritual:

Playing the game in DX11 mode avoids the crash successfully, but performance suffers dramatically, so it's not really an acceptable workaround.
