I build the application in windows 10, VisualStudio 2015, x86.
In chromium code:
gles2_command_buffer_stub.cc:
- Code: Select all
GLES2CommandBufferStub::Initialize(...)
...
bool offscreen = (surface_handle_ == kNullSurfaceHandle);
gl::GLSurface* default_surface = manager->default_offscreen_surface();
...
gl::GLSurfaceFormat surface_format =
offscreen ? default_surface->GetFormat() : gl::GLSurfaceFormat();
The 'default_surface' is nullptr.
Any ideas?
