Bug ID: 43786 Summary: The Witcher 3: textures disappear in some places when you move Product: Wine Version: 2.17 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: directx-d3d Assignee: wine-bugs@winehq.org Reporter: shtetldik@gmail.com Distribution: ---

Created attachment 59299 --> https://bugs.winehq.org/attachment.cgi?id=59299 The Witcher 3: Velen cave save with disappearing texture

In some areas when you move, textures toggle, disappearing and appearing back.

But they don't leave a transparent area, but rather just untextured surface when that happens. So I'm not sure if it's the same as other missing texture bugs or not.

I attach a save in Velen cave where that happens, as well as a video capture of that texture toggling.

Graphics:

OpenGL renderer string: AMD Radeon (TM) RX 480 Graphics (POLARIS10 / DRM 3.15.0 / 4.12.0-2-amd64, LLVM 5.0.0) OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.3.0-devel (git-3e54493265)

--- Comment #4 from Shmerl shtetldik@gmail.com --- Some report, this isn't happening with Nvidia blob, so it can be Mesa specific. I'll open a Mesa bug.

--- Comment #5 from Shmerl shtetldik@gmail.com --- I just got an idea, since this issue reminded me a similar problem in the eON wrapped The Witcher 2 (see https://bugs.freedesktop.org/show_bug.cgi?id=98238 ), I tried running the game with the Mesa variable proposed there:

glsl_correct_derivatives_after_discard=true

And it fixes the flickering! The problem is that it seems to also cause some performance hit. May be it can help narrow down the issue in Wine so it could be avoided?

If it's indeed the same issue, we could fix this in way very similar to the Mesa workaround, i.e., postpone discards until the last usage of derivatives in the shader.

--- Comment #9 from Shmerl shtetldik@gmail.com --- I found another example of a similar issue, with some face features like beards disappearing in the distance. And it's not fixable with setting glsl_correct_derivatives_after_discard=true

It seems to be a different issue. It could be useful to have instructions how to reproduce it.
