Kingdom Hearts 1.5 HD Remix [BLUS31212]

ATLANTICA/JAFAR ISSUES:

The issue here, of course, is the emulator seems to just present the last frame before you last opened the save/gummi menu while game is still being rendered behind it, it even has the stretching "underwater" effect on that frame when loading into Atlantica.

First time I loaded Atlantica(and Genie Jafar)  I used these settings, I dont' think all of them were necessary, because I was able to reproduce with different settings when I returned later:

CPU                                                                                   
PPU/SPU:   Recompile                                              
Threads:    1                                                                               
Firmware:   automatically load libraries                  
additional:  none

GPU
Renderer:      Opengl
Default Res:   1280x720
additional: Write color buffers/use gpu texture scaling/strict rendering/disable vertex


Every other time I tried to load this world these settings worked:

CPU                                                        
PPU/SPU:   Recompiler                            
Threads:    auto                                       
Firmware:   load liblv2.sprx only              
additional:  none

GPU
Renderer:     Vulkan
Default Res:  1280x720
additional:    Write color buffers/strict rendering

The settings that seemed to matter to get in to the world seemed to be write color buffers/strict rendering/default res (720p) everything else seemed to be your own preferences provided they worked on earlier worlds. If those don't work try the first set of settings I used, failing that, cry.
Additionally, once you're in the world and save the game, you can change your settings how you see fit, the only exception I found was I could not use default res 1080p, however I COULD default 720p but turn strict rendering off and use 150% render scale to still play at 1080p.

For agrabah I used the same settings as for atlantica the first time (with opengl) But since the bug had the same symptoms I suspect the second set of settings I used would work too.

The second time I went to Hollow Bastion, using the bubble to get the previously inaccessible underwater chest at the beginning of the world caused the same bug as with Jafar/Atlantica, and the same settings fix it, I'm not sure if the other bubbles can experience this bug or not, but I'd just use the atlantica settings until you're done with the Gateway of the World and Waterway sections.

Related to this, anytime a "spacial warp" effect was used (dark portals, xemnas) a similar affect was seen, but only within the "ripples" and distortion fields, I'm assuming the settings wouldfix it but I never bothered to test....

TL;DR: Use strict rendering/1280x720/write color buffers to load Atlantica/Jafar/Hollow Bastion bubbles.....

I wanna know how you managed to use both "Write Color Buffers" and "Strict Rendering Mode" without getting this error:

F {rsx::thread} class std::system_error thrown: device or resource busy: device or resource busy

Because I've tried your combination of settings and about 10 or so more and have no luck getting the game to continue without getting that anytime I pause or try to save. Usually happens after going to a different area after initial load.
