The code always assumed that the size of the image with the Y plane dimensions, which, while often the case, isn't correct. We remove the assertions that the display offset was always (0,0) and properly carry the actual data over IPC. Remoting the theora decoder and enabling fast video copy exposed several other related issues in the various D3D11 image types. Various WPT uses theora YUV44 images (because we do not support YUV444 H264 ones). Those images are made of 32 pixels planes with a display size set to 20 pixels. Prior P1D the backend image was a ShareYCbCrPlanar image which correctly handled the size settings. Like the image serializer, the various D3D11 images always assumed that the Y plane size was the image size. This however expose existing issues where the offset position of the display is completely ignored for some image type. See bug 1669054 All those problems explain why sometimes we displayed more pixels than we should have. Depends on D91914 Differential Revision: https://phabricator.services.mozilla.com/D92233
