Sreenshots do not save current screen content

[j4reporting]

It happens quite often, that taking a screenshot won't save the current content but some former frame from several seconds ago.
This is especially evident after level exit. Saved screenshot will not show the level end screen but some other frame.

WIn10/ Nvidia GPU + Vulkan present method = layered on DXGI Swapchain.

Cannot repro. Does it happen with the regular swap chain?

Can't say, because of issue #715
Will try to use the regular setting again and see what will happen.

Don't know how to trigger this. Usually, the first 1-2 screenshots (PNG) may save the wrong content, but consecutive screenshots then manage to grab the right content.
e.g. this happened yesterday after finishing the ritual episode.
End of episode credits (Congratulations etc.) respawned in start map. Reloaded the last savegame to hunt for remaining secrets.
Found the Ogre Gym ;) and took three screenhots inside of 3-4 seconds.
the first screenshot does show the end of Episode screen, displayed several minutes ago (w/o the text, though).

I can repro with a full screen DXGI swap chain. I do think this is an NVIDIA bug though, I have no idea how else to explain this.

Edit: Cannot reproduce without DXGI swap chain.
