[BUG]: Harry Potter and the Chamber of Secrets [SLES-51192] Mipmapping issues
Describe the Bug
Passing on an issue that a friend reported - not too familiar with the game but will try to offer info where I can. Mipmapping appears to cause texture swapping/corruption in various areas, showing incorrect texture for walls, building trims, and so on.
Moving the camera makes any affected areas cycle rapidly through various textures that are in memory in a way that almost looks like z-fighting (especially when it's flickering to textures that look similar to the intended one).
Software mode looks correct, native res in hardware is still affected. Mipmapping disabled is correct, but in this case it runs too slowly to be playable without mipmapping. Pics show software versus different angles of hardware.

Reproduction Steps
Loading into any level and looking around should suffice. The first level in the farm/barnyard type area shows it most on the brick walls in my images above - looking at them in hardware mode and moving the camera around should reproduce the issue.
Expected Behavior
Hardware renderer displaying normally without any garbled texture cycling.

I haven't played the game in a while but I can confirm that atleast on the gsdump you provided enabling gpu palette conversion fixes the bug.
Good stuff, can confirm this works. For anyone else having the same issue: I think this game has the Framebuffer Conversion fix in its automatic fixes, so when Manual is enabled the dispaly will look corrupted - enable Framebuffer Conversion manually, then GPU Palette Conversion, and everything will look as intended.
Reopening as this is still a valid issue.

This is not a fix.
