Intel's Unreleased 3.0 X.Org Driver Gets More Fixes For DRI3/Present
In particular, much of the work recently on the still unreleased xf86-video-intel 3.0 driver has been about Direct Rendering Infrastructure 3 and the Present extension. It's going on three years that the Intel 3.0 X.Org driver has been in development without being formally released and there's still no signs of it coming soon. The most recent development release, xf86-video-intel 2.99.917, is now 15 months old itself!
Anyhow, landing today in the xf86-video-intel Git DDX is a fix for a crash under DRI3. There have also been other DRI3/Present related fixes recently as well within the Intel Git.
