Looks like the drawing code is invalid and is rendering "part" of the requested images. Like the buffer is starting to draw few lines out of the display, and leaving few blank lines at the last lines of the display.
I've checked with factory image from https://github.com/Xinyuan-LilyGO/LilyGo-AMOLED-Series/tree/master/firmware and this one is working correctly, filling whole display.
This one can be easily verified by creating empty screen with textarea and aligning it to the top left. One can see that only part of the textarea is visible, mostly distinguishable by lack of rounded corners of corner.
