Any clue about what's this yellow flashing dot?

Nearly a full  year since this problem began, and still no game patch to resolve the issue. More than half of the eighteen Title Updates released for EA FC 25 have indicated 'stability fixes', and none have removed the irritating glowing and blinking large green pixel dot from the television screen. As described in every post, beginning last September 21st, the problem occurs in every Kick Off, Manager Career, and Player Career mode match, regardless of selected club, real or generic stadium, and happens on most platforms (Xbox Series X/S, Xbox One, Playstation 4, and Playstation 5; unaware if occurs on PC or Nintendo devices). Just today played a number of Manager Career mode games offline, and the issue is exactly the same. Apparently, this nuisance does not occur in Ultimate Team or other online game modes, otherwise, the community would have demanded a resolution by October. Since the problem occurs primarily in offline game modes, has continued to be ignored. Personally, will be verifying the issue has been thoroughly patched in EA FC 26, before paying EA Sports for any more beta version releases. Have already forgone purchasing Madden 26 and EA College Football 26 for similar reasons this year; far more bugs, glitches, and anomalies than acceptable from a multi-billion dollar enterprise. This company needs to address old game breaking bugs and glitches, before concerning themselves with adding features and content that no one asked for; i.e. POV camera cutscenes, removing the ability to manually create unique formations, failing to update or modify generic stadiums, etc., etc., etc. Recently, played a match against Union Berlin, and the co-op camera angles are still broken (showing upper light fixtures across the entire screen during matches), which has been broken since FIFA 16.

Only play Manager Career mode offline (disconnected from EA servers), and have noticed the same glowing green random pixel ball floating around the pitch. For me, generally is only located in the bottom right corner of the television screen, however, I use co-op camera settings. The majority of the time, occurs in certain Premier League matches, rarely appeared in La Liga EA Sports stadiums. Educated guess is a game coding monitoring device or tool utilized during gameplay testing by developers, that was not turned off, before the release of Title Update 4. Very annoying to say the least, and just another item to add to the bug/glitch list of problems arising from the latest update.
