When importing a PNG file onto an Image object in Capture, the alpha channel is not being retained. I have managed to get this working correctly before. The properties panel confirmed the file as "8-bit with alpha", and transparency was respected in the viewport. However, I cannot reproduce this consistently.
When I now import or replace the image, Capture shows the file as plain "8-bit" — no alpha — and the image renders without transparency.
Screenshot 1 Working state (alpha recognized)
The properties panel reads: 4534 x 3127, 8-bit with alpha The thumbnail shows the image with a transparent background (the black in the preview indicates transparency is present).

Screenshot 2 Current broken state (alpha stripped)
The properties panel reads: 1290 x 1696, 8-bit No alpha channel is recognized, despite the source PNG containing transparency.

Steps to reproduce
Question
Is there a specific requirement for Capture to recognize and preserve the alpha channel of a PNG? For example:
Any insight into what differs between these two cases would be very helpful. Happy to provide the source PNG files if useful for debugging.
Kind regards, Julian
