the screenshot doesn't capture them properly; otherwise, in my "correct" version, I get a game image with black rectangles on the sides.
if you reconstruct it, it looks approximately like this:
Attachment 73325
by the way, my screenshot from your example is actually in the "incorrect" aspect ratio because I only made the last one in the "correct" one. 🤔
Even in the last one, the image is stretched. It should not be stretched. This reminds me that you have an HD screen resolution, while the game itself has a resolution of 1024x768.
