Definitely need sdl version and kde / plasma version, also are you using multiple monitors? You could try the AppImage at https://releases.wildfiregames.com/rc/ , if it runs would be a strong indicator where to look further into the issue. The AppImage should also be easy to add to Lutris.

I heard this guy made it to WWI:

@hyperion @vladislavbelov Hey can you share more info about your hardware ? Depends on how you installed the game. https://gitea.wildfiregames.com/0ad/0ad/wiki/GameDataPaths

These 0 A.D. screenshots look incredible the graphics, unit details, and environments are really coming together. Love how each civilization feels distinct and historically rich. Can’t wait to see more gameplay footage and build up armies in them!
