From 279143c6e808b37c333321b696d80df77f709a04 Mon Sep 17 00:00:00 2001 From: "Owen W. Taylor" Date: Sat, 6 Jun 2009 14:46:22 -0400 Subject: [PATCH] Disable SGI_swap_control extension for DRI2 We currently don't have support for SGI_swap_control for direct contexts with DRI2, so disable reporting the extension. Reporting the extension, and then having glXSwapIntervalSGI() "succeed" but do nothing can confuse applications. https://bugs.freedesktop.org/show_bug.cgi?id=22123 --- src/glx/x11/dri_common.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/src/glx/x11/dri_common.c b/src/glx/x11/dri_common.c index 90c3d8c7d9d..6de41111134 100644 --- a/src/glx/x11/dri_common.c +++ b/src/glx/x11/dri_common.c @@ -345,7 +345,9 @@ driBindExtensions(__GLXscreenConfigs *psc, int dri2) #endif #ifdef __DRI_SWAP_CONTROL - if (strcmp(extensions[i]->name, __DRI_SWAP_CONTROL) == 0) { + /* No DRI2 support for swap_control at the moment, since SwapBuffers + * is done by the X server */ + if (strcmp(extensions[i]->name, __DRI_SWAP_CONTROL) == 0 && !dri2) { psc->swapControl = (__DRIswapControlExtension *) extensions[i]; __glXEnableDirectExtension(psc, "GLX_SGI_swap_control"); __glXEnableDirectExtension(psc, "GLX_MESA_swap_control"); -- 2.30.2
