Screen has strange looking streaks

I followed all the steps and when I use the terminal on my waveshare 7in5_v2 it gives off these streaks.
Sorry If it's mad basic I am quite new to using github

I'm getting a similar effect, just that it's like clouds or dirt coming gradually from the edges after having run the terminal.
On the "official" waveshare tests, I don't get those.

@PeterMcCann07 Out of interest, as you are using the same screen – is the typing speed you're getting anywhere near viable? I have full screen refreshes in something about 20 seconds or so ... not really usable.

Typing speed it's way too slow and if I use paperpi it looks super clean and refreshes a lot better, I'd love to sort this as it's decent enough but the encroaching black lines make it unusable after a while.
