When using VKD3D_CONFIG=descriptor_heap the game freezes at the very start of a mission. It makes impossible to close the game and even Steam stops working properly, so I need to exit Steam through the system tray to close both programs. Sometimes it doesn't crash for a couple of minutes but then there's a very noticeable visual bug that consists in white light flickering all around the map. I tried to record this visual bug but now I can't reproduce it, it just crashes.
