Comment 1 Darren Hart 2014-02-18 16:44:34 UTC 
This is a known issue with the binary emgd driver. There isn't anything we can do about it other than wait for an update from the EMGD graphics team.
Comment 2 Ross Burton 2017-07-05 10:53:58 UTC 
Waiting For Upstream status is being removed, changing to Accepted.
Comment 3 Randy MacLeod 2019-06-13 15:22:40 UTC
