Quality of displayed oscillogram.

[av_disp]

Hello,
I have a question regarding the quality of oscillogram displayed by the oscilloscope ( the screenshot is attached).

The wave generator  generates  slow square wave, the channel 1 is connected straight to the wavegen 1 output. But when you examine the signal you see those yellow areas surrounding the leading and trailing edges and that's a bit confusing.  What is this and is there anything I can do to get rid of it?

Actually, I don't believe that it has anything to do with the signal itself (but I am not an expert), I would think that this is simply how the picture is drawn on the screen.

Thanks!
