From 9119be1dd1681e56147bc1d5cba637dd466e849f Mon Sep 17 00:00:00 2001 From: Tony Crisci Date: Sat, 5 Aug 2017 10:41:05 -0400 Subject: Remove unnecessary calls to glActiveTexture Since wlroots shaders only use one texture at a time (ie there is only one sampler2D variable in any shader), it is unnecessary to switch between active texture units at this time. --- render/gles2/surface.c | 2 -- 1 file changed, 2 deletions(-) (limited to 'render') diff --git a/render/gles2/surface.c b/render/gles2/surface.c index 33d8b0dc..8a92907f 100644 --- a/render/gles2/surface.c +++ b/render/gles2/surface.c @@ -51,7 +51,6 @@ static bool gles2_surface_attach_shm(struct wlr_surface_state *surface, surface->wlr_surface->format = format; surface->pixel_format = fmt; - GL_CALL(glActiveTexture(GL_TEXTURE0)); GL_CALL(glGenTextures(1, &surface->tex_id)); GL_CALL(glBindTexture(GL_TEXTURE_2D, surface->tex_id)); GL_CALL(glPixelStorei(GL_UNPACK_ROW_LENGTH_EXT, pitch)); @@ -76,7 +75,6 @@ static void gles2_surface_get_matrix(struct wlr_surface_state *surface, } static void gles2_surface_bind(struct wlr_surface_state *surface) { - GL_CALL(glActiveTexture(GL_TEXTURE0 + 1)); GL_CALL(glBindTexture(GL_TEXTURE_2D, surface->tex_id)); GL_CALL(glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR)); GL_CALL(glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR)); -- cgit v1.2.3
