Why does my Rectangle Marquee Tool have rounded corners in Photoshop?

[Othmane_El achouri8692]

I don’t know why, but every time I use the Rectangle Marquee Tool in Photoshop, the corners appear rounded instead of sharp. It’s caused me a lot of problems — I just want to create a simple frame around an image with straight edges. I’ve already tried all the suggested solutions I could find, but nothing worked. Any idea what might be causing this?

What do you see if you view the selection in Quick Mask mode?

What you are showing is Stroke controls for a rectangular Shape layer, not the Rectangular Marquee tool.
