BUG AND UPDATE FIX DESCRIPTIONS:

Persona 5 Royal - one of two blockbuster releases this month, launched with some mysteriously black battle scenes in Vulkan. vonchenplus identified this as missing support for special OpenGL-style clear commands which are not supported by the Vulkan specification, and added a workaround to skip clearing in this case. More work remains to be done to properly implement these clears in Vulkan, but this allows the game to be playable.

Bayonetta 3 - Longtime graphics contributor Blinkhawk has returned from the dead to fix games. The other major release of this month, Bayonetta 3, came out, and to users’ dismay, it did not work in yuzu. After defeating the services issue causing it to freeze, Blinkhawk investigated and fixed a rendering issue causing it to appear white in Vulkan.

Super Mario Galaxy - A new challenger approaches! Or rather, a new showing from some older games, Super Mario Sunshine and Super Mario Galaxy. While rendering bugs were fixed in Vulkan, and OpenGL with the GLSL backend, they are now fixed with the NVIDIA-exclusive GLASM backend, as byte finally acquired some NVIDIA hardware for testing and development.

MONSTER HUNTER RISE - The second issue was causing MONSTER HUNTER RISE to fail to render most scene elements. yuzu has had a workaround in Mainline for over a year! However, this papered over this issue, which is why it took so long to get fixed. byte[] fixed this issue as well, and now all is working as intended – there are no more known issues with the macro JIT! Speaking of MONSTER HUNTER RISE, Blinkhawk contributed another fix for the rendering in this game, implementing the ASTC 10x5 format. Grainy textures begone!

Luigi's Mansion 3 - byte[] found that while he was debugging graphical issues, yuzu would frequently crash after the merge of Project Y.F.C. He narrowed it down to some code that was improperly ported from our friends at the Skyline emulator and implemented a fix, finally allowing him to debug without worrying about the game’s rendering speed causing any issues. Now, a user’s PC performance won’t be a cause for crashes. Maide and Morph were on top of two regressions from the merge of the 3D registers pull request from a few months ago. Morph found that the merge was causing many shaders to be recompiled unintentionally, and narrowed it down to a different default value for the tessellation parameters in the register definitions. Meanwhile, Maide and byte[] worked together to find a strange rendering problem affecting Luigi's Mansion 3, and finally found the issue in the values of the stencil mask registers.

TRIANGLE STRATEGY - vonchenplus found an issue with how a compute shader for TRIANGLE STRATEGY was being compiled by yuzu’s own shader recompiler project, and implemented a fix by deleting a broken optimization pass, returning blocky rendering to normal.

Snack World: The Dungeon Crawl - Gold - Still on a roll, vonchenplus also implemented 1D texture copies. Normally, the guest driver (the GPU driver included with each game) has to provide what kind of texture type is in use in memory, but thanks to the previously mentioned open documentation NVIDIA provides, we now know that there is a way to set the correct kind when the memory is initialized. The end result is much improved rendering in Snack World: The Dungeon Crawl - Gold.
