Platform / OS / Hardware: Linux Mint 22.1 (based on Ubuntu 24.04)

Flycast version: RetroArch core (AppImage), version 5866e97

Hardware: AMD Ryzen 5700U, using its Radeon Vega 8 integrated GPU

Description of the Issue

If Vulkan is selected as the video driver inside RetroArch, then Flycast tends to crash when opening the frontend menu and navigating through settings (like shaders or core options). Issue also happens when fast-forwarding. It does not happen with OpenGL video driver.

Debugging Steps Tested

• Load game using Flycast's RetroArch Core
• Open RetroArch's menu (F1 key)
• Navigate through and inside some menus, like shaders or core options
• Flycast crashes
• It's more frequent when booting a game and during its first moments after boot
• It's more stable after a few minutes, but still happens
• Opening and closing the menu a few times may be needed for the crash to occur

Oh, nothing at all. I just thought because it keeps happening with flycast. If it's not the case, then I shall close the issue. As a last request, could you suggest where should I open the issue? The main RetroArch repo? Or is it more suited to another one?

Yes, the retroarch github: https://github.com/libretro/RetroArch/issues
