From dbb2d192de33064ae6cdb799d71c5ac89a6ea8ff Mon Sep 17 00:00:00 2001 From: Zack Rusin Date: Thu, 24 Jan 2013 17:48:12 -0800 Subject: [PATCH] glx: only advertise GLX_INTEL_swap_event if it's supported Only drivers supporting DRI2 version >=4 support GLX_INTEL_swap_event. So lets mark it as such otherwise applications which use this extension (i.e. everything based on Clutter, e.g. gnome-shell) break horribly on drivers supporting DRI2 versions only up to 3. Note: This is a candidate for the 9.0 branch.
