All games have graphical corruption with Vulkan on RetroArch

[PoloniumRain]

Platform / OS / Hardware:

RetroArch 1.19.1 on PC, Windows 11, AMD Threadripper 3960X, RTX 3080 (latest drivers)

Description of the Issue

Graphical corruption in the form of many small flickering blocks, shown in the videos below. I've tried 12 random games so far and it affects each one. RetroArch Shaders have an effect on it, but it also always happens without shaders. So Vulkan is unusable because this problem is always visable. Depending on the game and area it will sometimes have less or more graphical corruption when a shader is either enabled or disabled. I also have the D3D11 shader problem mentioned in #1612, so GL is only thing that's working for me.

Debugging Steps Tested

• Clean install of RetroArch with default settings.
• Default Flycast core settings.
• I've also tried many different core settings. None have any effect.
• D3D11 has graphical corruption but only with shaders enabled.
• GL works fine with or without shaders.
• Older Nvidia drivers from 5+ months ago also have this issue
