I'm running Endeavor OS on my desktop PC, with a RTX 4070 TI. I got lsfg-vk from the AUR via the lsfg-vk-git package. However, I was able to verify that the pacman package from the github also results in this issue.
On both RPCS3, and PCSX2, lsfg-vk does work, but I noticed that when attempting to quit the emulator, it freezes and requires to be killed through btop. Both emulators are set to use vulkan.
