[BUG]: Dumping Creates Duplicate Textures With Non-Unique Name Hashes

Describe the Bug

Several games when dumping textures will produce tens of thousands of textures in a few seconds of dumping. Ace Combat 4, 5, and Zero are known culprits. In these cases there are dozens of identical files for each unique texture. When the dumped PNG files are checked for similarity they are identical in every way except for name. There appears to be something wrong with the hashing algorithm that generates different names for identical images.

For example the following images are identical but the first portion of the image name hash differs.

Reproduction Steps

Run a mission in Ace Combat 4, 5, or Zero and turn on texture dumping. Thousands of ground textures will fill the dump folder.

Expected Behavior

Identical images in graphics memory should have a single unique hash.
