From a627a4be50045c539c6d21bb14ea863a3a84a40f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Sergio=20G=C3=B3mez?= Date: Thu, 23 Mar 2023 12:38:38 -0500 Subject: [PATCH] libweston/input: Fix assert for valid confine region MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We need only check that the region is not empty. If either the input region or the constraint region have degenerate extents, the intersection from the previous instruction will set confine_region->data to pixman_region_empty_data.
