Today I'm seeing some font corruption for the letter P in some of the text shown on the Home, Voice and Multi- Pad pages. It's evident on both the upper and lower case letter P and only on the fonts used in those pages. Rebooting doesn't fix the problem. Those characters appear as if broken apart and not completely unlike Japanese kanji might look.
Hi Stu ..
I have had this before, and it has gone away.
I first noticed it after I updated a FW with (accidentally) USB1 plugged (one underneath)
Personally, I unplugged them rebooted and it went away.
Some characters Broken APART, like you say.
