And without EUI it does not happen?
It sounds like your game is missing a picture-file... but then you would also have an error message, saying one dds file is missing.
Do you have any other DLC-like mods enabled (copied in the DLC folder)?
I think you should try a reinstall of Civ and EUI. If something is missing or messed up from other things you did before, reinstall will solve it.
Before reinstall you can also upload the lua.log, database.log and xml.log
