From 32013abae63f1c31598ac716acd7e73c24fadae1 Mon Sep 17 00:00:00 2001 From: Genki Sky Date: Wed, 30 May 2018 20:11:58 -0400 Subject: rootston: xdg-shell*: Fix get_size() for newly-mapped views The user-visible issue is that newly-mapped xdg-shell* windows would sometimes start with their top-left-corner, rather than their center, in the center of the screen. This is because get_size() would conservatively fall back on (width, height) == (0, 0) if both set_window_geometry() had not been called, and it found view->wlr_surface to be NULL. But, view->wlr_surface is only set to non-NULL in view_map(). We call get_size() before this. Fortunately, the wlr_surface in question is accessible via view->xdg_shell{,_v6}->surface, so always fall back on that. We can assert its presence instead of further falling back on (width, height) == (0, 0).
