[Qemu-devel] no mouse events with gtk,gl=on

[Rob Herring]

I'm running current master of QEMU using virgl and display backend
"gtk,gl=on". I get no guest mouse events unless I force CONFIG_GTK_GL
off or make the following patch. Key events work fine. I'm on ubuntu
16.04 with GTK 3.18 (ubuntu 15.10/GTK 3.16 also had the same issue).
I've had this problem for some time, but just getting around to trying
to debug it further.

         }

Any ideas or suggestions how to debug this further?
