Flycast: Graphical Glitch - Galaxy S7 (Exynos) Android Oreo- Vulkan Driver

[tabnk]

On Vulkan (Default Setting + WS Cheat), it have Graphical Glitch in all games. OpenGL is fine.

Example:
Virtua Fighter 3.

It's only happening on this platform so this is probably a Vulkan driver bug. I believe the Galaxy S7 has a Mali GPU so do you know the version of the Mali drivers used by your phone?

Check if a graphics driver or android update is available for your phone.

Vulkan API 1.0.61
Version (hash) a4c0bd09.

It is latest version for this device.

DriverVersion: 659.11.3337

There is still a chance for the OEM to update the GPU drivers on Exynos S7 models, since it's currently getting quarterly security updates. But to be honest, it might not be a huge driver update because the Mali-T880 GPU used by your phone is quite old (was released in late 2015) and Vulkan versions beyond 1.0 need at least Android 9 Pie anyway.

BTW, are you using stock ROM from Samsung or a custom ROM e.g. LineageOS?

On Stock Oreo 8.0.

Saw a youtube video with LineageOS PIE driver had slower gaming performance than Stock so no point to install.
