Hi,

We are using weston 1.9.0.  GENIVI IVI extension is 1.9.1 version.
Karthik, please correct me if I am wrong. And you would need test code all the reported issues?

Regards
Annamalai

Hi,

Which wayland-ivi, weston and wayland version are you using ?

Can you send me a minimum example source code which reproduces these issues ?
