I think I have found the cause of many of the menu ghosting issues on my Glo:
There is a new feature setting available in firmware 3.15.0:
Code:
[FeatureSettings]
LeanAndMean=false
The default, at least on my Glo, appears to be LeanAndMean=true, so setting it to false fixes the ghosting issues.
It could be that the default on other devices is different. I suspect the feature is to give a choice of cleaner or faster sceen painting (although I haven't noticed any slowdown when I changed the option to false), but there might be other effects. Like any of these unofficial options, use at your own risk.
