Bug ID: 58700
           Summary: Regression: Direct3D applications show a blank screen
                    under wined3d in 10.15
           Product: Wine
           Version: 10.15
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: d3d
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

As of Wine-staging 10.15, all Direct3D applications only render a blank (often
black) screen while still producing sound and reacting to inputs.

This issue was not present in 10.14, downgrading to it fixes the problem.

Multiple Unity games seem to have consistently produced this issue.

Arch Linux, latest packages up to 2025/09/14.
KDE Plasma 6 Wayland session.
Both X11 and Wayland Wine backends seem affected.
AMD A8-5500B with Radeon HD 7560D.
No Vulkan support whatsoever.

Confirmed for non-staging 10.15 for these Unity games:
https://bugs.winehq.org/show_bug.cgi?id=56614 The Signifier
https://bugs.winehq.org/show_bug.cgi?id=56936 Blood West

Cursors render upon menus loading.  Otherwise black screen for all other
graphics.

Audio plays and hidden menus are responsive to cursor hover and clicks and
keyboard inputs.

Both work for 10.14 (except Signifier menu video bug still open)

For the PlayOnline application, I've bisected c3f3ef24e8d [1] to be causing the
same behaviour.

No cursor is visible for that one, but it also seems otherwise functional.

Thank you!

Thanks for regression bisect.

Regression only affects OpenGL renderer, per commit details.

Vulkan backend for vanilla WINE renders graphics for both games, enabled via:
winetricks renderer=vulkan

Both games seem to run on Vulkan consistent with OpenGL renderer prior to
regression.

Gameplay lag for Vulkan seems to match OpenGL lag.

Signifier video also still not playing for Vulkan as for OpenGL.

Reproducible e.g. with Leisure Suit Larry - Wet Dreams Dry Twice demo on Steam.

This does not only occur in Unity-based games.

This might be the same thing as the new behavior of bug 58491 and possibly
fixed with https://gitlab.winehq.org/wine/wine/-/merge_requests/8972

The patch works for me and solves the problem in all Unity games that I know
were affected.
For games that were also affected and do not use Unity, however, the fix does
not work. That will need a separate bug report I guess.

Confirming patch fixes both Signifier and Blood West Unity games.

Works for me for the PlayOnline Viewer case.

Thank you!

Thanks everyone, I'm going to mark this as fixed with
9cdfa803cd1f971bdf03667c86698685c913e97c

Béla if you still experience some issues with other games please could you open
a new bug? Or maybe just mention which one, I've tried Leisure Suit Larry but
couldn't reproduce any issue with current HEAD.
