XnView Software

Hello.

I am pretty new to XnView. Just got a new Mac ( Mac Studio ) with MacOS Ventura 13.1 and installed XnView 1.4.0
I downloaded three years of images from my phone, which I want to put in order.
So, a three panel view. I have the folders / tree structure on the left, icons in the middle and preview on the right.

The entire XnView screen flickers rapidly while it is reading the contents of an image folder of a hundred to maybe two hundred images; then settles down; but flickers when I hover from one image to the next, or do anything in the UI.

It is like the whole UI reshades itself between two statuses, brighter and darker. For unknown reason.

Well, I guess we have to chalk it up as a fluke.

I figured I would screen record it. And, once QuickTime started recording, no flickering in the app. Closed QT. No flickering in the app.

Restarted the system, opened XnView ... and all is well

It just reshades and highlights the expected area going from one image thumbnail to the next.
