I saw that ubuntu mate 18.04 has included mate 1.20 and with that marco and DRI3 is present.
But on my machine i still get screen tearing on my laptop with ubuntu mate 18.04 with intel gpu and marco on, i see that DRI2 and DRI3 is active but marco still does not use DRI3: xdpyinfo | grep DRI
DRI2
DRI3
Is there any news on this to be fixed?
