ICS Photo editor weird behavior I have just installed CyanogenMod and, while testing the Gallery and Photo editor apps, have noticed a very strange behavior. Whenever I try to apply some effects such as Lomo, Documentary among others, the Photo editor applies the effect only to a circle in the center of the image. The problem happens with any image from my gallery, no matter the resolution or the camera (back or front camera). 

I have already rebooted the system, and have tried to "clear data" of the app. I have searched all the possible configurations and could not find anything related to this problem.

(The funny thing is that I tried an app called Photo Editor ICS, which is a clone of the original Photo Editor, and it worked fine. But I don't mean to keep using it, I expect that the original app works)
Try using Aviary instead. 
It's an excellent photo-editor app with even more features than the default one, and it works for me, even when I flash experimental JB roms where the camera doesn't even work.

This is a strange problem, unique to your device, and you should probably report it on the CM forums.

HTH!
