Issues with Cyanogenmod

1.Stock camera has rotated preview and does not take pictures

2.Notification bar sometimes gets stuck and becomes unusable

(The camera can be partially solved by replacing Gallery2.apk with GalleryGoogle.apk from eg a Nexus S stock JB4.1.2 ROM which allows you to take photos, but the preview is still rotated)
(Notification bar can be fixed by removing "debug.fb.rgb565=0" and "debug.composition.type=mdp" from build.prop)


Everything else works fine 

if you find any problems feel free to post them  i will have them rectified ASAP
