Hi all Just noticed this today when using the OneNote MUI app on my new SP3: When OneNote starts (either using pen button or app icon) the wheel is fine, but if you multitask out of it and then back again (including to the desktop), usually the transparency of the quick control wheel is like the top screen shot. Edit: App is not docked with any others, and is in "fullscreen" mode, in either landscape or portrait. Anyone else able to confirm / replicate or offer advice ? Have uninstalled and reinstalled the latest version of the app, same story. Weird !
