Every time I run the .exe to my game, the window shrinks every time. In Project Settings, it is defaulted to Windowed at 960x540. Under Standalone Player Options, I have User Player Log, Visible in Background, and Allow Fullscreen Switch, and Use DXGI Flip Model Swapchain for D3D11 all checked off with supported Aspect Ratios of 4:3, 5:4, 16:10 and 16:9.
Here's an example of what happens:
1st Launch: window size is intended 960x540, play game for however long, close game
2nd Launch: window size now looks slightly smaller? maybe im seeing things, play game, close game
3rd Launch: window size is definitely smaller and now everything is getting pixelated because of how small the window size is
4th, 5th, 6th launch and now the window size is only big enough to show the minimize, and close buttons
