You nailed it. I can't remember how many manufacturers it was. I thought one because they were all caps with an X on top
the marking on top of a capacitor are purpose built weak/failure points so if the cap overheats the pressure can be released there, in a controlled failure, as opposed to becoming a mini-pipe bomb.
Often, I think, its an X, sometimes a manufacturer might use another letter like K or T though.. I dont know why, presumably something with branding.
