Description

Determine WebGL back-buffer on Mali-400 GPU DrawingBuffer tries to allocate back-buffer as GL_RGB texture in case of requested alpha attribute is false and fails because GL_RGB not supported on specific GPU's (e.g Mali- 2/3/400 family). This CL manages plumb the GPU workaround from chromium side and choose texture format correctly. BUG=449150
