Hi,

Weston has some repainting problems for clone mode, but extended should
definitely work. What did you have to change? Is Weston buggy or is it
something in your drivers needing different handling?

Also, why specifically 1.0.1? All 1.0.x should be compatible
protocol- and API-wise.

If you have any problems with Wayland or Weston, 1.0 or master
branches, it would be nice to report them, so people can at least look
at them.


Thanks,
pq
