Ar Tonelico Qoga : Knell of Ar Ciel [BLES01102]

nope, its some kinda emulation issue, for the black screen in battle try this: open up the menu and drink a potion, for me that fixed it lol, for the random crashes theres no solution yet :/

Tried this trick today and yeah, it helped to fix black screen in the fight (and get eternal white screen right after the fight)

Also, for me Vulkan works a little more stable than OpenGL but gives 10-15% less FPS: Vulkan commonly crashes with eternal black or white screen (or may be goes into loop, and I'm not sure the problem is in graphics renderer), in addition to this OpenGL also often fails with "Access violation"; Vulkan have never done so yet. Unfortunatelly I cannot try DX12 on my Win7.
