Research direction
Start at Xenko.Graphics.CommandList.MapSubresource and trace the WriteDiscard path used by Xenko.Graphics.FastTextRenderer.End. Reproduce the win-vulkan run with the Starbreach project, then verify that GameProfilingSystem.Draw completes without the WriteDiscard exception and profiling text still renders.
