I'm using a 2012 MacBook Air running macOS Catalina (10.15.1), and everytime I try to play Minecraft, the game loses focus every 10 to 30 seconds. It'll act like I switched to a different window, but no other window is even open. I've rebooted numerous times, and I even reinstalled the game just now, and the issue still persists. I'm not sure if this is an issue with Minecraft, My computer, or Java.
