wallpaper issue in landscape mode (launcher and lockscreen) topic

Hi everybody,

Im currently cooking a rom and now i have this very strange issue.
In stock android (4.4.2) landscape mode was blocked for both lockscreen and launcher.

I then went on and replaced the lockscreen and the launcher, and added "log.tag.launcher_force_rotate=VERBOSE" to build prop.
Now both can be rotated just as i wanted it, but however when i rotate to landscape mode, wallpapers are resized incorrectly, leaving a black bar on the side :confused:
Wallpapers are 2160x1920. Have a look at the screenshots to know what I mean!
Using some kind of live wallpaper (like muzei feg) the issue doesnt appear
Anyone knows where this comes from? I found several threads with this issue with google but no solution...

thanks in advantage!
