I had no issues so far..@Sam Nakamura
Hey sam, I'm on official RR too.
In my case, with google wallpapers i can set previously dwnld pics as wallpaper....
But when i try to set pics downloaded after kernel flashing, as wallpaper, it says
"Unable to load wallpaper. Image is either corrupted or unsupported ".
I flash stock kernel again & download same image & try to set it as wall. No issues!!
Can u check on ur side too plz..
Also with quickpic app, there are problems while sharing images too... but not when using Simple gallery
Quick solution, download Madlog or Catlog from store, replicate the issue and record logs and post them here if you have hints that issues are kernel related..
