Screen flashes briefly without touching anything

On Tuesday I was using LRC v13.5 with no problems. On Wednesday I installed v13.5.1 and ever since then I have had intermittent moments when the screen flashes briefly a couple of times without me touching anything. I am using a dual monitor setup and twice when this happened the main display and the secondary monitor display of LRC switched monitors. I am using a MacBook Pro 2023, Apple M3 Max chip, 36 GB memory, Sonoma 14.6.1. Thanks in advance for any ideas.
