Traktor screen turns white after start

Wolfgang Sauerbraten

My Traktor screen turns almost all white after a little while, after i've launched it. What can I do to fix this? I can restart Traktor, but the white-out situation soon recurs. I realize that i'm running Traktor 3, and that Traktor 4 is generally recommended for Mac Sequoia (15) at this point, but I'd rather avoid the upgrade if i can. Is there anything else I can try?
Hope I've provided enough detail. Thanks in advance for any help!

P.S. : I don't use any kind of controller. I use Traktor to record podcasts, and simply load tracks onto the decks and click to play.
