one thing to watch with these screens is the viewing angles!! as they are super cheap, they also have rubbish viewing angles.

The are designed to be viewed from slighlty below center, with the chip at the bottom of the screen. You can see the colour inversion that happens in this rather shoddy video i did

your mileage may vary though

Hey kite. Ignore the above. I found the files in /lib/modules/4.4.50+/kernel/drivers/staging/fbtft. I copied the new ones you supplied across and hey presto, the junk at the side of the screen is gone! There are still.... 2? Lines of junk at the bottom though so then I thought I'd try a rotate and sure enough, when rotated 90 degrees, the corruption is gone completely!

So that means I'll have to have the pins at the top of the screen, rather than the bottom, but it's a small price to pay! Thank you so much for your help!

Edit. As I was writing this, you were also replying! So thank you, and apologies for the crossed wires!
Ah awesome glad to hear! Yeah I only worried about rotation, when mine arrives I can try it out but it's at least in the right direction :)

Yeah, I think if the image moved down (right?) 2 more rows, it would work without rotation BUT as moosepr has just stated, I'm very surprised that with 90 degrees of rotation on, the image (text especially) appears clearer. So though it is effectively upside down compared to what moosepr has shown us, it seems the better for it.

Everytime I've said 90 degrees. I've meant 180. Forgive the brain melt. It's been a long day!

Moosepr, may I just ask, the 2 piezo's you've hooked up. Are they just wired straight to the Pwm gpio pins?
Unsure as to whether or not to bother with sound on something so small.

Yeah they are just wired straight to the gpio, no amp, no filter. You can hear them, but they are not great. You can hear the static a little bit
