I tested on the rockchip, on i915 and on vc4 with igt plane_cursor_legacy and kms_cursor_legacy and I didn't see any regressions. I couldn't test on MSM and AMD because I don't have the hardware I would appreciate if anyone could help me testing those. v1 link: https://patchwork.kernel.org/cover/10837847/ Thanks!
