Depth buffers problems on Android devices with Adreno GPUs #639

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago
There is a known issue on Adreno GPU's, where if the last rendered object 
turned off depth writing, it would trash the depth buffer.

Solution:

call:
GLES20.glDepthMask(true);

before any glClear()'s of the depth buffer.

The only glClear happens in clearBuffers() of OGLESShaderRenderer.java. Putting 
it right before glClear() solves the issue.
