Early Access Bug Reports - Black screen with Vulkan renderer, with CRIT error log - Forum

When starting POE2, I get a CRIT error log saying:

"

2025/09/23 22:37:00 11992044 ae9aab97 [INFO Client 32] [VULKAN] Init SwapChain = 2560x1440
2025/09/23 22:37:00 11992044 393b6718 [CRIT Client 32] [VULKAN] unsupported backbuffer image count

After enabling more logs, this happens when vkGetPhysicalDeviceSurfaceCapabilitiesKHR reports minImageCount=4.

Here is the exact info queried by vkGetPhysicalDeviceSurfaceCapabilitiesKHR:
