Not sure if it's the right place to report or if already been reported (tried reading the last 4-5 pages of the thread), sorry...
Version 8.12.0 worked great with Android 7.0.0 (Nexus 6) but is experiencing drawing issues (main startup screen not disappearing once start button is clicked) as well as selected app hard freezing randomly after updating to Android 7.1.1. Seems to happen even if no speed hack is being applied (speed hack causes almost instant freezing though).
Thanks for all your work.
