This is a game bug, but I can work around it.

It's entirely stupid. The game locks mip 1 then unlocks mip 0 and expects it to upload -- so then when it renders it does mip filtering between 0 and 1 and 1 hasn't been uploaded which makes this funny transparent catgirl.

Should be fixed now!

Hi @Joshua-Ashton,

I retested on Vol.0 (since you have that game) and the issue is fixed by d39cf31 / b658cae however fa988be appears to break it again to a lesser extent:

fa988be	b658cae	WineD3D

Overall transparency is much lower with fa988be, when characters tilt their heads some transparent layering effects can also be seen.

This was tested on Proton 5.0-8-RC1 w/ DXVK Build [#1311](https://git.froggi.es/doitsujin/dxvk/-/jobs/1311) and [#1310](https://git.froggi.es/doitsujin/dxvk/-/jobs/1310)

Could you try it with my branch: https://github.com/K0bin/dxvk/tree/mark-dirty-in-lock?

EDIT: nevermind, this code has been merged to master.

ZZereoX 2020-06-15 github

I confirmed that all 3 Nekopara titles (Vol. 0, 1, 2) are now displaying correctly when using DXVK master (291f7e0).

Closing... Thanks.

(Sorry for the delay I was on vacation this past week.)

I confirmed that all 3 Nekopara titles (Vol. 0, 1, 2) are not displaying correctly when using DXVK master

Are they still broken or did you mean to write 'are now displaying correctly'?

ZZereoX 2020-06-15 github

@K0bin Yeah, sorry that was a typo. They are indeed rendering correctly. I'll edit my comment to make the correction. Thanks.
