Shadow of the Tomb raider creates a fullscreen swapchain that exceeds the monitor size by 1 pixel in both dimensions. Buffers for the swapchain must be created with the requested size, and the mismatch between buffers and swapchain causes pixel-wide lines of uninitialized data along the bottom and right display edges. Vulkan allows creation of a swapchain that extends beyond the advertised capabilities, but warns that the results are platform-dependent. However, doing so eliminates the lines.
The real question though is what happens on Windows. E.g. for d3d9, what happens is that the content is stretched to the window size on Present().
