Focus Game Engine. This is Stride/Xenko fast-tracked for Phr00t's Software games. Improvements over the original Focus on Vulkan support, PC platforms, VR, performance & ease. Cherry-picks commits from other forks as needed.
When creating a simple white texture for use as a shader resource, Vulkan ends up complaining about quite a bit:
Error: [ VUID-vkCmdPipelineBarrier-pMemoryBarriers-01184 ] Object: 0x1be37261a88 (Type = 6) | vkCmdPipelineBarrier(): pBufferMemBarriers[0].srcAccessMask (0x4000) is not supported by srcStageMask (0x1). The Vulkan spec states: Each element of pMemoryBarriers, pBufferMemoryBarriers and pImageMemoryBarriers must not have any access flag included in its srcAccessMask member if that bit is not supported by any of the pipeline stages in srcStageMask, as specified in the table of supported access types. (https://www.khronos.org/registry/vulkan/specs/1.1-extensions/html/vkspec.html#VUID-vkCmdPipelineBarrier-pMemoryBarriers-01184) ([0] Validation)

The white texture starts to get made here: https://github.com/phr00t/xenko/blob/master/sources/engine/Xenko.Graphics/GraphicsDeviceExtensions.cs#L92
