I saw that I don't send command 0x2c to tell the screen "new frame will come" it doesn't draw whole new frame but move current frame and draw new single line over it. It looks like moving video tapeI don't want to dig deep into the details of this thread, but for example ST7789 (other as well I guess) requires only to set it up once, then you can only throw raw image data at it (CS could me hardwired to GND as well. but DC now can stay in one state all the time) and having for example full screen updates, it will start to draw a new frame when you overflow its SRAM - memory pointer will loop to SRAM's start.
