Icon on the taskbar that got changed are smaller...

Hello everyone,

I do not know why it is like this but icon that are not the original that come with programs look much smaller on the taskbar

and yes I am sure I download the icon at the maximum size 512 if I am not wrong and checked it on several computers

here a picture to demonstrate:


here is the site with the icon:

from a test I did the icon on my taskbar show with 24 pixel size when it should be 32 pixel and I just do not know how to fix it

I think its an optical illusion ,the 2 you marked are round and the others are square ,I enlarged the photo and place 2 rulers across the top and bottom of the icons and the differences are minute at best ..
