This is an oversight in eec9c3a2f63555604dd6e357bb3280e82e14ff5b: vk_format specifies the format used for the frontend resources. The backend images could use a different format, depending on what the swapchain supports.
Also, introduce the terms "frontend" and "backend" for the two sides of the swapchain, which are probably easier to understand. --- dlls/dxgi/swapchain.c | 20 ++++++++++---------- 1 file changed, 10 insertions(+), 10 deletions(-)
