Hiya,
I have had this bug a couple times, it generally has happened when i resumed my tablet from sleep while it was still on PL (but it does not always happen).
Im on a samsung galaxy tab 10.1 running honeycomb 3.2 build number: HTJ85B.UEKMP P7510UEKMP
Here are some screen shots of how it looks:
Hope this helps!
