Bug ID: 42819
           Summary: The Witness: transparency problems
           Product: Wine
           Version: 2.6
          Hardware: x86-64
                OS: Linux

          Severity: normal
          Priority: P2
         Component: directx-d3d

wine screenshot

Many objects ingame like grass and trees are rendered as blocks instead of
having parts of them transparent.

With wine 2.6 the game has become playable (when MSAA is off), it would be
great if this could be fixed to improve the aesthetics.

Your best bet would be to attach theterminal output you receive while this
iissue ocurrs.

I'll be submitting my logs later today.

terminal output

Here is the output on Mesa git + Radeon RX 470. Perhaps it's something related
to unhandled dcl_input_ps* opcodes.

Terminal output, Wine 2.6

This is the terminal output for my machine:

Nvidia 970 GTX using the proprietary drivers version 378.13 with Wine set to
Windows 7 mode running the 32-bit version of The Witness.

I too experience the blocky looking trees and grass..

This seems to be caused by unimplemented alpha-to-coverage.

ATOC is also one of multiple issues reported in bug 21253 (arma 2)

I have a question, could ATOC be simply implemented alone or should it be
implemented after global multisampling support ? (I ask this because wikipedia
describes ATOC as multisampling technique)

--- Comment #8 from Józef Kucia  ---
The transparency problem in The Witness should be fixed now when MSSA is used
and multisample textures are enabled:

Please open bugs for remaining issues.

Tested with the last wine-git version, and it is fixed.

I added the registry entry Software->Wine->Direct3D->MultisampleTextures as a
DWORD = 1 and ran the game with "2x MSAA".
Without MSAA you get the blocky rendering as before.

Tested with different resolutions, settings, MSAA levels.
Grass looks as "correct rendering" and puzzles can be seen from any distance.

Thank you.
