Dear All,
I have backported following patches from wayland 1.11.0 to 1.9.0 to test one crash issue [1] . I am able to backport and start Weston with it. Is this valid thing to do? https://cgit.freedesktop.org/wayland/wayland/commit/?id=6d29c0da3cd168e08187cd204d2314188479c0f1 [client: Introduce proxy wrappers] https://cgit.freedesktop.org/wayland/wayland/commit/?id=6fe12f02e3b4879cd3d5faa08f023cc761d13be9 [client: Fix wl_display_roundtrip_queue() race condition] https://cgit.freedesktop.org/wayland/wayland/commit/?id=69ec70fb0d3f75f4bcce449238d6297f6a986b5f [tests/queue-test: Add tests for proxy wrappers] -- not required. Now If I understand it correctly I need to use/modify code where the wayland client creates the proxy and sets the queue. One such components is [2] ILM control library. I tried to do as per the patches but with it nothing is coming on display even though weston starts successfully with ivi-shell and ivi-controller.so. Attached here the modified file. I would like to understand if the way I used is correct or not? Could someone explain this fix and How to use it properly for ILM control library? Do I need to add similar fix in qtwayland 5.5.1 and other such components (e.g. wayland sink from gstreamer) ?

Thanks & Regards, Vikash
