From 1e44247baaf433b13416dfef8a05540f0c8dd6e1 Mon Sep 17 00:00:00 2001 From: Rouven Czerwinski Date: Fri, 3 Jan 2020 07:36:33 +0100 Subject: [PATCH] xwayland: handle size_hints == NULL In case xcb-iccm is not installed on the system, size_hints will be null. Handle this as if the get_constraints functions was not implemented and return the defaults.
