https://www.w3.org/Bugs/Public/show_bug.cgi?id=27513 --- Comment #3 from Dongseong Hwang <dongseong.hwang@intel.com> --- @kbr, thank you for explaining. WebGL spec defines how readPixels, toDataURL, texImage2D and drawImage work. We made consensus that ImageBitmap should behave like them. It means ImageBitmap should copy the drawing buffer (i.e. back buffer). It might be good for WebGL spec to mention ImageBitmap in below sentence. https://www.khronos.org/registry/webgl/specs/latest/1.0/ """ This default behavior can be changed by setting the preserveDrawingBuffer attribute of the WebGLContextAttributes object. If this flag is true, the contents of the drawing buffer shall be preserved until the author either clears or overwrites them. If this flag is false, attempting to perform operations using this context as a source image after the rendering function has returned can lead to undefined behavior. This includes readPixels or toDataURL calls, or using this context as the source image of another context's texImage2D or drawImage call.
