users with new computers. Only known solution is
LIBGL_DRI3_DISABLE=1.
This is your obligatory "I told you so" for when the complaints start
rolling in half a year from now.

I'm concerned that we may have enabled DRI3 before it was fully-
baked,
if it's known to be broken with Firefox, WebKit, LibreOffice....

Hi,
This is a heads-up that the change to enable accelerated compositing
always has landed in WebKit trunk and will be landing in rawhide soon.
As previously discussed, the DRI3 plus modesetting driver combination
is known to be broken in accelerated compositing mode as per [1].
WebKitWebViews will most likely not be functional in F25 for affected
users. Any help in fixing [1] would of course be appreciated. The
relevant upstream WebKit developers are not very interested in this
problem because Debian doesn't use DRI3.
