The single-pixel buffer protocol is used to allow wayland clients to easily draw solid-color rectangles by presenting a 1x1-pixel buffer and scaling it to the desired size. This patch improves how these buffers are then handled in the scene-tree renderer. We already ignore opaque black rectangles at the very bottom (and anything under them) because we assume we'll be rendering on a black background. This patch detects black opaque single-pixel buffers and handles them in the same way as black opaque rectangles. It also renders single-pixel buffers as rectangles rather than buffers because this is probably more efficient in the underlying renderer. In wlr_scene_surface we cache whether the attached buffer is a single-pixel buffer. This is done because the wlr_single_pixel_buffer_v1 will be destroyed after texture upload, after which it becomes much more annoying to check if the buffer is a single-pixel buffer. |
