From e7788c22eed7d307a8d123792bec21d8a948cfd6 Mon Sep 17 00:00:00 2001 From: Brian Ashworth Date: Fri, 8 Mar 2019 12:44:42 -0500 Subject: output_damage_whole_container: damage subsurfaces This adds an iterative call in `output_damage_whole_container` to damage the subsurfaces for all visible views that are inside of the container. This is needed to damage subsurfaces that extend outside the box of the container. Without this, those subsurfaces will create artifacts when moving or resizing. --- sway/desktop/output.c | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) (limited to 'sway/desktop/output.c') diff --git a/sway/desktop/output.c b/sway/desktop/output.c index d7d3fc07..54b9f294 100644 --- a/sway/desktop/output.c +++ b/sway/desktop/output.c @@ -473,6 +473,17 @@ void output_damage_box(struct sway_output *output, struct wlr_box *_box) { wlr_output_damage_add_box(output->damage, &box); } +static void damage_child_views_iterator(struct sway_container *con, + void *data) { + if (!con->view || !view_is_visible(con->view)) { + return; + } + struct sway_output *output = data; + bool whole = true; + output_view_for_each_surface(output, con->view, damage_surface_iterator, + &whole); +} + void output_damage_whole_container(struct sway_output *output, struct sway_container *con) { // Pad the box by 1px, because the width is a double and might be a fraction @@ -484,6 +495,12 @@ void output_damage_whole_container(struct sway_output *output, }; scale_box(&box, output->wlr_output->scale); wlr_output_damage_add_box(output->damage, &box); + // Damage subsurfaces as well, which may extend outside the box + if (con->view) { + damage_child_views_iterator(con, output); + } else { + container_for_each_child(con, damage_child_views_iterator, output); + } } static void damage_handle_destroy(struct wl_listener *listener, void *data) { -- cgit v1.2.3
