Last good build #5797 (0.0.6-7935)
First bad build #5785 (0.0.6-7947)
Vulkan: VK_ERROR_DEVICE_LOST
OpenGL: gfx corruption
After PR #5785, when accessing book withing the game (Read the Wizards's Companion):
Vulkan - After opening the book game freezes with the error RSX: class std::runtime_error
thrown: Assertion Failed! Vulkan API call failed with unrecoverable error: Device
lost (Driver crashed with unspecified error or stopped responding and
recovered) (VK_ERROR_DEVICE_LOST). RPCS3 is not frozen and clean exit is possible.
OpenGL - Gfx gets distorted (sample image included). After closing the book,
gfx returns to normal.
Same issue with all PPU/SPU Decoders. Logs done using PPU LLVM/SPU LLMV.
Vulkan:

rpcs3-v0.0.6-7947-12dc3c18_win64-Vulkan.log.gz
OpenGL:

rpcs3-v0.0.6-7947-12dc3c18_win64-OpenGL.log.gz
Also, same issue presists in latest PR #5840 (0.0.6-7981).
I confirm that accessing book in NiNoKuni is actually broken (Win10, i7 7700, gtx1060)
You should check to see if it still appears in latest kd-11 PR. https://github.com/RPCS3/rpcs3/pull/5860
I have tested this issue yesterday with rpcs3-v0.0.6-0b0fe8bf-kd-11/master from PR #5860, but it was not resolved, so I did not comment here.
Now that you suggested to test that PR, I noticed that F line now points to line vkhelpers.h:964, not to vkhelpers.h:832 from rpcs3-v0.0.6-7947, if that is relevant at all.

Also, OpenGL is the same as before.
Maybe some future additions to that PR will resolve it...
The PR added more code to vkhelpers.h which pushed the offending line downwards into the file. Nothing about the error itself changed.
@k10kan Hi, kd asked to group #5785-related issues together a bit, so could you please close this ticket and copy the original report over to #5869 instead? You can do this easily by clicking on Edit, copying everything out, and just pasting it in as a comment to the other ticket.
Sure.
@nitrohigito Please, update problem description in #5869 from "a (certain?) book" to "the book from main menu (Wizards's Companion)". That is the only book in Ni no Kuni as far as I know.
I have added a picture as well.
Ok, thanks for clarifying that bit, I wasn't sure.
