Recent (25.3.1) Radeon drivers for Windows break LBP1 on Vulkan with MSAA on 5700XT

Hello. My GPU is an 5700XT. Starting with the Radeon driver 25.3.1 for Windows released on the sixth of March 2025 (so merely a month old at the time I'm writing this, it's in fact the current "recommended" driver (I don't recommend it)) Littlebigplanet [BCES00141] is broken graphics-wise with MSAA antialiasing enabled (see attached pictures). With MSAA disabled it's also, though to a lesser extent, broken in a different way (glass, including the Pod side windows, as well as score bubbles don't look correct), so naturally I seeked to get AA to work, which I knew it could because it did before I updated my drivers. So I do suspect it's merely a driver bug, but as this emulator is the only use case scenario where I noticed it I am posting it here, also to let others know. I know that these GPUs had a hard time with antialiasing in the emulator, but the issue was as far as I can tell fixed. I don't know if it's that same issue, but if it is, then with new drivers it became unfixed. Default settings were applied in the driver, although I tried tweaking some of them as well, to no avail. Using OpenGL the issue is not present, but as ever the performance is subpar compared to Vulkan.

System: RPCS3 v0.0.36-17745-613212f9 Alpha | master. ASUS STRIX 5700XT, AMD 3700X, B550 chipset, 16 GB RAM. Windows 11 Pro 24H2 build 26100.3476.
Last working Radeon driver: 25.2.1.  First non-working Radeon driver: 25.3.1.
Last working Vulkan driver: 2.0.317. First non-working Vulkan driver: 2.0.331.
The driver 25.3.2 does not work correctly either, I checked.
