Not seeing that problem on my Note9 running Android 10 while browsing a folder of 4K+ images.

I have File loading priority set to speed and Show images in the highest possible quality enabled in Settings.

I was able to replicate the issue on my S21 FE (Qualcomm ver. Android 14) with a test file with the size 2894 x 10413 (30.1 MP) formatted as a PNG.
The File loading priority setting has no effect, but turning off Show images in the highest possible quality partially fixes the issue.

• With the quality setting on, the app lags and stutters (scrolling past the image stutters, zooming in and panning is slow and at a low framerate).
• With the quality setting off, the app hangs for a second when scrolling to and away from the image, but the other issues go away.
