From 2b418b4d8857a4eacd719b76dfd36210383db6d6 Mon Sep 17 00:00:00 2001 From: Simon Ser Date: Mon, 31 Aug 2020 16:38:39 +0200 Subject: [PATCH] examples/dmabuf-capture: add extra roundtrip for wl_output listener This example was relying on wl_display_dispatch being enough to fetch output information. This worked by chance. Add an explicit wl_display_roundtrip. Other examples don't setup wl_output listeners, so they should be fine.
