The program is very slow, especially with raw photos, and occasionally doesn't display them properly.

Environment:

• OS: [Windows 10] latest 22H2 update
• qView version: [6.1, 2023-08-16]

Information:
qView takes about 4 or 5 seconds to load a 6000x4000 .CR2 image (20-30MB) from an SD card with 4,500 images, while the Windows photo viewer takes less than 1.5 seconds. Even with JPEGs it feels a tiny bit sluggish.

Sometimes raw images appear corrupted or blank, but then are fine after you go to a different image and come back. This seems to only happen when flipping through photos in the program, not when opening them from File Explorer.

Also I can't use any of the mouse buttons as shortcut keys, that seems like an oversight as opposed to a bug.

This is tracked here.

This unfortunately might be a place where the libraries I am using to open images are not as fast as other libraries, which is a major re-engineering effort. That is just a guess, though.

Very interesting... can you send a test image if I get a chance to look into this in the future?
