Tv Guide transparent background

Hello,

not sure if this is intended to be like this, but after the recent update, when i open the "Guide" on my tv, the background is now transparent, which makes it very hard to read the guide.

The central block with the program timeline is ok, with black background, but the lower part, with the plot or the info on the program, is completely transparent and doesn't allow an easy reading.

Is there anything i can do to fix this?

Thanks
