I've seen the discussion elsewhert about YouView units, but have experienced a new appearance in some of my HDR2000T menus for the last few days.
For example, the menu for the Opt button used to have a black highlight against a light background, but this is now bright white. Entering text for a search used to have a white background, which has now vanished, making the whole thing very hard to read.
I have tried adjusting transparency, but this does not improve matters.
Is this an "improvement", misbehaving software, or am I losing my marbles?
