I observed that /system/build.prop lacks the ro.sf.lcd_density property.
I added it because I usually want a higher density (430 DPI) to see more (Lollipop introduced big blank spaces, I hate seeing less on a 5" screen than what I saw in Gingerbread on a 4" screen)
I can test some specific error you have to check if editing the build.prop solves it, if you want.
You’ll have to discuss this with the devs. If I recall correctly there was a fix that made it into beta testing but caused other problems so it didn’t make the final release. But maybe I’m confusing this with some other bug atm.
I’m sure they are still working on it.
