[Bug 107117] mesa-18.1: regression with TFP on intel

--- Comment #22 from Olivier Fourdan <fourdan at xfce.org> ---
Some more info, this is related to the use of "glamor"...

xserver-1.20 + modesettings DDX + glamor : FAILS
xserver-1.20 + modesettings DDX + w/o glamor : OK

That explains why intel DDX works, it doesn't use glamor.

Same with Wayland, weston started with "--use-pixman" (which disables
acceleration in Xwayland as well) works, whereas weston with Xwayland and
glamor acceleration fails as well as Xorg with modesettings and glamor
acceleration.

Now, I don't know if the issue is actually in glamor or in mesa...
