I've tried messing with some of the properties within the SkinManager and even tried using the DrawAlphaImgList method to give the images a Blend value but none of that worked. I dug through the forum to see if anyone else had this problem and found this where this person seems to have the same problem.
Reasons of these issues are different.
Try to use the sSkinManager1.Options.StdImgTransparency property, this solution must work in your case, I think.

I've tried using that but that still won't fix the issue. Are there any other properties that need to be set in the ImageList for that to work? For some more context, we're using the GetBitmap32 method to load the images in the list into an empty image in our form. I've tried setting the transparency of the image to true, I've tried different drawing styles for the image list and different blend colors and different bk colors but none of that has fixed it.
This capture is from a previous build of our software and the image has the intended transparency. The method used to display the images and the images themselves haven't changed at all but the transparency stopped working when we updated from 10.15 to 11.21.
