Hi and thanks for good project, got the following issue:

Midle 1/3 part of screen is filled using last 1/3 part of image: https://photos.app.goo.gl/NrU67cK5Pw3RJGog6
build board using gerber files from June 04 2020

If change
dev->fifo_conf.tx_fifo_mod = 1;
to
dev->fifo_conf.tx_fifo_mod = 0;
or play with clock dividers i managed to get 2 dragons. But can't get correct image
