Root cause: support cards update dxwrapperConfig.renderer, but ContainerUtils only copied the dxwrapperConfig string while applyToContainer writes the Wine Direct3D renderer registry value from ContainerData.renderer. The affected report therefore saved renderer=vulkan but Wine still logged 'Using the OpenGL renderer' and repeated 'Unhandled interpolation mode 0x3'. This change synchronizes ContainerData.renderer from dxwrapperConfig when that key is applied (app/src/main/java/app/gamenative/utils/ContainerUtils.kt:428) and adds a regression test (app/src/test/java/app/gamenative/utils/CommunityConfigApplicationTest.kt:176).


Summary by cubic

Fixes the WineD3D renderer not matching the configured value when support cards update dxwrapperConfig.renderer, so Wine now uses the requested renderer (e.g. vulkan) instead of falling back to OpenGL.

Bug Fixes

  • Syncs ContainerData.renderer from the renderer key in dxwrapperConfig when that config is applied.
  • Adds a regression test covering the renderer update.

Written for commit 104cd19. Summary will update on new commits.

Summary by CodeRabbit

  • Bug Fixes
    • Applying a graphics configuration now updates the container’s renderer when the configuration specifies a non-empty renderer, while preserving the existing renderer if none is specified.

📝 Walkthrough

Applying a dxwrapperConfig now updates ContainerData.renderer when the parsed renderer value is non-empty. A test verifies that both the configuration string and renderer field change from gl to vulkan.

Changes: dxwrapper renderer update

Layer / File(s) Summary
Apply and test renderer updates
app/src/main/java/app/gamenative/utils/ContainerUtils.kt, app/src/test/java/app/gamenative/utils/CommunityConfigApplicationTest.kt
The config application sets the container renderer from a non-empty parsed value. The test verifies the updated configuration string and renderer field.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~8 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to 104cd

A malformed community config can now prevent that config from being applied. The issue is limited to malformed input, so merge risk is low, but the handling should be fixed or accepted.

Guard malformed dxwrapperConfig before reading renderer.

A malformed community config such as version=2.4.1,renderer can reach this branch. KeyValueSet.get("renderer") then throws because the final entry has no =. The exception is caught by the community-config application flow, so it prevents the configuration from being applied, not container creation. Preserve the existing renderer when parsing fails.
