Ok I figured out the setting that was causing the issue. It was the following setting: "MinimalWindowSize=720 480". After changing it back to the default "320 240" the window stopped moving when changing pictures. I'm going to detail my thought process of how and why I ran into the bug because it happened as a result of trying to work around a different bug that results from working with small images. I'm working with 32x32px png files for a retro game so I disabled HighQualityResampling to keep...
I'm experiencing the same issue.
