VK_ERROR_SURFACE_LOST means the window or display surface the Vulkan game was rendering to became invalid. This commonly happens when alt-tabbing out of a fullscreen Vulkan game.
How to fix it:
- Switch to Borderless Windowed mode instead of exclusive Fullscreen — this prevents surface loss when alt-tabbing
- Update your GPU driver — newer drivers handle Vulkan surface recreation better
- If using multiple monitors, try disabling the secondary monitor while gaming
- Disable Hardware-Accelerated GPU Scheduling in Windows Display settings
- Don't alt-tab during loading screens — Vulkan surface loss is most common during resource transitions
- For games with Vulkan launch options, try adding '-w' or '-windowed' to force windowed mode
- Check if your display cable is secure — a momentary disconnect triggers surface loss
