From 44a13b4e767eef1985a4a34723b7cc279e1dc160 Mon Sep 17 00:00:00 2001 From: Richard Grenville Date: Tue, 10 Dec 2013 22:06:02 +0800 Subject: Feature: Add XRender-GLX hybird backend - Add new backend "xr_glx_hybird", which uses X Render for all compositing but GLX on the last step of rendering to screen. This makes GLX-backend-specific VSync methods usable while may avoid certain bugs with GLX backend. The idea comes from ali1234. Experimental. - GLX backend: Stop using or rendering to depth buffer. - Use glFinish() instead of glFlush() before VSync. It probably uses more CPU but could be more reliable than glFlush(). --- opengl.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'opengl.c') diff --git a/opengl.c b/opengl.c index 33a2fc724..d557aea63 100644 --- a/opengl.c +++ b/opengl.c @@ -124,7 +124,8 @@ glx_init(session_t *ps, bool need_render) { if (need_render) { glx_on_root_change(ps); - // glEnable(GL_DEPTH_TEST); + glDisable(GL_DEPTH_TEST); + glDepthMask(GL_FALSE); glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE); glDisable(GL_BLEND); @@ -880,7 +881,7 @@ glx_set_clip(session_t *ps, XserverRegion reg, const reg_data_t *pcache_reg) { glStencilOp(GL_KEEP, GL_KEEP, GL_KEEP); glColorMask(GL_TRUE, GL_TRUE, GL_TRUE, GL_TRUE); - glDepthMask(GL_TRUE); + // glDepthMask(GL_TRUE); } cxfree(rects_free); -- cgit v1.2.1
