[libretro/Android] Core crashes when game is loaded (GPU error)

[DJtheMan2101]

Game or games this happens in

All

What area of the game / PPSSPP

OS: Android 15

With the default core options, the libretro PPSSPP core crashes when loading a game in RetroArch. The logs seem to indicate a graphics error with both the OpenGL and Vulkan video drivers.

What should happen

The core should not crash.

The crash does not happen when software rendering is used. It also does not occur on the standalone PPSSPP app, only the libretro core.

Logs

These are RetroArch logs. There is one for gl and one for vulkan.

I'm also seeing this on Linux (x86_64). My log is attached.

I have a crash too on Linux when trying to start a game with the PPSSPP Libretro core (RetroArch) and using the Vulkan renderer. When starting a game, I get a black screen for a split second, then it crashes to desktop.

• Having Vulkan as a renderer in the general RetroArch settings (renderer of PPSSPP inherited): crash to desktop
• Having the glcore OpenGL renderer set instead (with PPSSPP inheriting it): the games start properly
• Having the Vulkan renderer in RA's settings but OpenGL set in the PPSSPP core settings: the games start properly too

Using RetroArch as a flatpak on Xubuntu 24.04. RetroArch log here: https://pastebin.com/sjgzXEJF

EDIT: worth noting that the issue doesn't happen with RetroArch as an AppImage, so it might be a flase flag (issue with the flatpak sandboxing not really related to PPSSPP or something like that).

EDIT 2: I've found a game that also crashes to desktop with Vulkan (and not with OpenGL) when using RA as an AppImage, so the situation is not as straightforward as I thought.

Hi,

I can't reproduce the issue on Xorg and Vulkan with Nvidia using latest RA (328e4ce) and PPSSPP (8509e95).

I can't reproduce the issue on Android 13 using Vulkan with RA 1.21.0 and PPSSPP (8509e95) on Adreno 540 which can do Vulkan 1.1.0. I tested with the cube test.

Thank you.
