some Google apps partly black
firstly, I have been googling my problem for hours and still not been able to find someone with the same issue. So don't be angry if someone already asked about it, thank you.
Yesterday I upgraded my phone from Helly Bean 4.2.2 to Helly Bean 4.3 (build from 08/14/2013), flashed GApps and SuperSU (factory reset included) and so far everything is working fine, except Google Search, GMail, and the Stock email app. Whenever I open a mail, half of the screen is black, and after some seconds, the missing UI parts appear. GMail has similar problems. In Google Search, whenever I click the search button on the keyboard, the search bar disappears (black bar) and reappears after I started scrolling.
I have some build.prop mods applied, but on 4.2.2 they were working just fine.
Does anyone know how to get rid of the black bars?
Thanks for your help!
