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.
