Tidy Cauldron (2708320), a Unity game, uses EnumWindows() to find the first window in the current thread and maximizes the window when changing to windowed mode. However, before this patch, the IME UI window and the DXGI fallback device window are on top of the game window at creation and thus they could get maximized instead. This causes the game window to lose focus and freeze. --- dlls/d3d11/tests/d3d11.c | 2 -- dlls/dxgi/factory.c | 1 + 2 files changed, 1 insertion(+), 2 deletions(-)
