Description

When I copy & paste or upload a 32 bit depth image into issue, ref it using !! format, and export to pdf file, the image can not display in the file, just leave a large blank area.
But a 24 bit depth image goes right.

I tested with the attached PNG image (image-with-alpha.png) that has an alpha channel, but I could not reproduce the issue. Could you provide the image that is causing the problem in your environment?
