Especially the control cards + switches panel buttons. Need to investigate options and possible investigation (e.g. touch area extending over the bounds of the buttons themselves, checking touch calibration on the gx50 to ensure the top pixels are touchable, etc).

Also, Matthijs noticed that the opacity animations of the controls+switches buttons are not synced - fix this as part of this task also.

Should also investigate (as part of this task) why some touches get lost when navigating through Settings page.
