I shared the settings with you @maxmp. An update regarding the bug: I couldn't reproduce the bug through the "inactivity" method I mentioned earlier; but the issue persists everytime when I switch to PA Eq from a different app when visualization is set to full screen. Depending on how you switch apps, the bug might behave differently. If you use bottom gestures to switch apps (like in iOS) then after switching back to PA the Visualization will not switch to full screen even though its been set to full screen (I have to tap screen once to start full screen Visualization). If you use navigation button to switch app then hidden controls won't be displayed after switching back to PA.
