[Flutter GPU] Fix Android/GLES crashers. by bdero · Pull Request #172588 · flutter/flutter

bdero · 2025-07-22T22:40:37Z

Continuation of #165630.

Resolves #164278.
Resolves bdero/flutter_scene#35.
Partly fixes: #160948.

Fixes OpenGLES crashers.
- Threadsafe GLES pipeline creation.
- Threadsafe GLES texture creation.
- Fix GLES internal float texture formats.
- Encode GLES passes on the raster thread.
- Overwrite GLES textures on the raster thread.
Fixes vulkan memory leak (flutter_gpu - potential memory leak on Android (Vulkan) #164278).

        break;
      case PixelFormat::kR32G32B32A32Float:
-        internal_format = GL_RGBA;
+        internal_format = GL_RGBA32F;


Does some form of capability checking already exist for these?

Fixing the enum values here sgtm though.

Err, doesn't look like it. I suppose it's GLES 3+ only.

      TextureDescriptor desc);

-  TextureGLES(std::shared_ptr<ReactorGLES> reactor, TextureDescriptor desc);
+  TextureGLES(std::shared_ptr<ReactorGLES> reactor,


Let's document the argument. Something like, "Whether the calling thread has a reactor worker.". Or something that ties the usage to the way the reactor works.

Thinking about this some more, can't this value be implicitly determined using ReactorGLES::CanReactOnCurrentThread?

Added docstrings.

So long as we have the concept of "untracked" handles (which I'm not really a fan of), it would seem that we'd need to punt this responsibility onto the user of the API, since only the user can know if they're going to destroy the texture off the GL context thread.

In either case, I tried this just for kicks, and CanReactOnCurrentThread segfaults while attempting to acquire the mutex lock for some reason... :(

I can take a look at the crasher. Can you file an issue for that?

SGTM, I detailed the crash here: #172880

- flutter#172588 has been included in 3.38. So it excludes that was applied in 3.35.3. - Added the `--no-lto` gn option. - `flto` for linux was added but it have been disabled in Flutter CI due to build performance issues. - flutter#176191 - flutter#177660 - flutter#177694 - If we want to apply the flto option, we need a container with an updated toolchain. tool: flutter-tizen/flutter-tizen#714 embedder: flutter-tizen/embedder#134 flutter-tizen/flutter-tizen#687
