Image preloading isn't working for me

[xkww3n]

Windows OS version

Windows 11 25H2

ImageGlass version

9.4.1.15 (64-bit)

ImageGlass release

Classic

1️⃣ Steps to reproduce

1. Enter Settings > Image
2. At Image Booster section, change "Number of images cached by Image Booster (one direction)" to 5, change "Maximum image file size to be cached (in megabytes)" to 300
3. Click Apply then OK, restart ImageGlass
4. Enter a folder that has several ~260MB TIFF images
5. Open the first image, wait seconds then navigate to next image

2️⃣ Actual behavior

The next image still take seconds to load, before that it only shows blurry mosaic.

Open Task Manager, and seen that ImageGlass only takes less than 1000MB RAM. Obviously it's not preloading 5 x 260MB image.

3️⃣ Expected behavior

The next image should load at full resolution shortly.
