ask for help about multi-display in wayland

[Xu, Jack]

We'll find time to update it and test the bug.
In fact, we tried to update to date 0821 and 0918, both had errors. 

Thanks,
Jack

Ok, I'm not familiar with EMGD.

(EMGD has their own fork of libwayland?)

Sorry, I meant, can you reproduce this issue with the master branch git versions of libwayland and weston, or are they somehow incompatible with the rest of the system you have? That's a pretty old Weston, can't you at least use the 1.0.4 releases of both? 1.0 series could get bug fixes still.


Thanks,
