Well, if the problem is over, then I think there's no need to dwell on why it happened in the first place. Sometimes it's just luck :D
Sometimes it's the videocard (all kinds of weird alpha glitches), sometimes it's weird electrons playing a prank on you.
I'd suggest to move on (taking note of the proper steps defined on how to avoid the problem next time, if it comes back).
PS: Yeah, the ClearTextureFilters(), followed by loading your sprites with the proper flags you want should work too.
Good luck with your project!
