Yeah CM for our Z1C seems to have small attention from developers and community.
I use it for some time now and could not find any bugs.
Currently (since build cm-11-20140521-NIGHTLY-amami) the hardware video decoding is broken. So you can not play any videos in youtube or webbrowser. If you use MX Player you can switch to software decoding which helps out for some videos.
