On Steam / Linux I have never had any issues until today, card in my hand drawn face down. When I played it, the front doesn't load correctly and it gets stuck on the stack, even though the game engine played it correctly and I was able to get to the end of the game, the broken card stayed on the stack the whole time.

This happened two games in a row, in the first game I just ignored the face down card in my hand but in the second game I tried to play it and it turned into a broken looking Cloud, Midgar Mercenary. The card stayed stuck on the stack but the game proceeded like it had come into play, i searched my library and played another equipment before the game ended. In the screenshot you can see another face down card in my hand, probably another Cloud but IDK.
