That "glitch art" looks like a video-card driver problem to me. It's also possible that the solitaire site uses more texture space than your card/driver can handle causing issues. The Aframe examples you linked seem to be simple geometric shapes with no textures so you may just be getting lucky there. Also, Phaser, the library GP is using uses Pixi.js for the webGL drawing code if I remember correctly and Pixi is supposed to fall-back to plain canvas rendering if webGL isn't supported -- so disabling WebGL for the site may make the solitaire site work.
