From 179d6f8087ba2b052a2d34c9c1ffc9fd6a710c48 Mon Sep 17 00:00:00 2001 From: Henri Verbeet Date: Thu, 1 Sep 2011 20:20:54 +0200 Subject: [PATCH] wined3d: Remove a redundant compare in IWineD3DSurfaceImpl_BltOverride(). If the source surface isn't on the destination swapchain it can't be a backbuffer there either. --- dlls/wined3d/surface.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/dlls/wined3d/surface.c b/dlls/wined3d/surface.c index a06030b3025..619bc92f401 100644 --- a/dlls/wined3d/surface.c +++ b/dlls/wined3d/surface.c @@ -5312,8 +5312,9 @@ static HRESULT IWineD3DSurfaceImpl_BltOverride(struct wined3d_surface *dst_surfa return WINED3DERR_INVALIDCALL; } - /* The only case where both surfaces on a swapchain are supported is a back buffer -> front buffer blit on the same swapchain */ - if (dstSwapchain && dstSwapchain == srcSwapchain && dstSwapchain->back_buffers + /* The only case where both surfaces on a swapchain are supported is a + * back buffer -> front buffer blit on the same swapchain. */ + if (dstSwapchain && dstSwapchain->back_buffers && dst_surface == dstSwapchain->front_buffer && src_surface == dstSwapchain->back_buffers[0]) {
