The conflict between ProfilesX and Tweaker is, that both
try to hide the builtin in profile status bar menu.
The issue with the control panel comes from the control panel
showing a screenshot while it is loading the screenshots are
cached at
/home/user/.cache/launch/com.nokia.controlpanel.pvr
Just remove this file after removing a control panel plugin
(like ProfilesX) and it will create a new one with out the
ProfilesX icon.
