vkd3d traces near the hang (10 MB, several seconds, with relative timestamps)

I've got same error on nvidia gtx770 сard 
Wow 8.2.0 30993 (Jul2 2019) 
kernel 5.0.0 
nvidia driver 430.26 
wine-tkg-staging-esync-vkd3d-opt-git-4.10.r9.g3bba6934 
vkd3d git b59b6b87 (2019-06-18) + d3d12_command_list_invalidate_bindings patch
that prevents wow flickering. 

On entering naz'jatar picture freezes, however mouse& sound are still working.
Window manager reacts to its key bindings with several seconds timeout. (Second
seat with second nvidia card is extremely slowed down too during this time). 

NVRM: Xid (PCI:0000:03:00): 31, Ch 00000014, intr 10000000. MMU Fault: ENGINE
GRAPHICS GPCCLIENT_L1_0 faulted @ 0x0_00000000. Fault is of type FAULT_PDE
ACCESS_TYPE_READ 

I've coollected vkd3d traces near the hang (10 MB, several seconds):

I think that the investigation starting point is near '1562358506.895769
