From df048973732fc856c9aa6ca2ca1de016b1386289 Mon Sep 17 00:00:00 2001 From: Furkan Sahin Date: Sun, 23 Sep 2018 15:17:36 -0400 Subject: swaybg: fix increasingly smaller bg on hotplug render_background_image alters the scale that cairo uses. Depending on the image mode, resolution, and image size, this may cause the surface to be rendered increasingly smaller. By calling cairo_save and cairo_restore, any changes to the cairo settings by the function are not kept as a side effect. The surface that swaybg uses is also now cleared before rendering a frame. This is needed to avoid artifacts on resolution or scale changes with certain combinations of image modes, resolutions, and image sizes. This was also part of the increasingly smaller background visual since it made it so it was not obvious the region being rendered to was smaller and caused an increasing number of smaller images to be appear for each hotplug. --- common/background-image.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'common') diff --git a/common/background-image.c b/common/background-image.c index f3d2551e..5ede55e3 100644 --- a/common/background-image.c +++ b/common/background-image.c @@ -58,6 +58,7 @@ void render_background_image(cairo_t *cairo, cairo_surface_t *image, double width = cairo_image_surface_get_width(image); double height = cairo_image_surface_get_height(image); + cairo_save(cairo); switch (mode) { case BACKGROUND_MODE_STRETCH: cairo_scale(cairo, @@ -116,4 +117,5 @@ void render_background_image(cairo_t *cairo, cairo_surface_t *image, break; } cairo_paint(cairo); + cairo_restore(cairo); } -- cgit v1.2.3
