I took a look at the project and as far as I can tell it doesn't use any images over 4096x4096.
This doesn't make any sense: the originally reported error said it was creating an image over 16384px, but there aren't any such large images in the project.
My best guess is it's a graphics driver issue. Linux often has poor quality graphics drivers that cause all sorts of problems. Maybe try updating the graphics drivers, or try installing alternate drivers if you can find any others available.
The project also uses the Spriter plugin which is a third-party addon - it's possible it's causing the issue somehow, but that would be the responsibility of the addon developer.
