When a compositor uses color transforms (ICC profiles) the output's postrender buffer is in the display's color space, not sRGB. A screenshot client receives this buffer and saves it as an untagged PNG, which appears oversaturated in non-colormanaged viewers. To fix this without altering the semantics of the raw output source (which must deliver the exact hardware scanned buffer, including overlays and direct scanout), add an optional, compositor driven scene-per-output capture source. This source re-renders the entire scene graph for a given output with an identity color transform (sRGB), using a hidden headless output to avoid flicker. The new function `wlr_ext_image_capture_source_v1_create_with_scene_output()` takes a wlr_scene, a reference wlr_output (for dimensions, scale, renderer/allocator), and an optional wlr_output_layout (for correct positioning). The source is created on demand in the existing output capture manager when the compositor has called `wlr_ext_output_image_capture_source_manager_v1_set_scene()` and `wlr_ext_output_image_capture_source_manager_v1_set_layout()`. If the compositor never provides a scene, the manager continues to create the original raw output source, preserving backward compatibility and hardware plane capture for compositors that need it. |
