Saving an RGBE9995 texture slice to PNG fails (all pixels transparent)

[reduz]

Description

Attempting to save a texture slice in RGBE9995 format to PNG fails, resulting in transparent image.

Steps to reproduce

Take a RGBE9995 texture being inspected and save it:

Result is a transparent texture (pasted here, but its transparent..):

Texture should expected to be visible (converted to RGB).

Environment

• RenderDoc version: 1.29
• Operating System: Ubuntu
• Graphics API: Vulkan
• GPU: Gefocre 1650

I am also unable to reproduce this. I don't have your exact case, but saving an RGB9E5 texture to png works as expected to me, the pixels have proper data and aren't transparent. I can't tell if your png was intended to be black-transparent and that's the bug, or if you just had transparent pixels with valid data in RGB and it's been corrupted somewhere on the way to the github issue.

(image resized for visibility, here's the original: ).

Can you please share a full and complete reproduction case I can use to reproduce your exact issue, as it may be something more specific than you have detailed here.

If you have another system available, it would also be helpful to check on a different driver or GPU in case this is a driver issue. You didn't say which driver version you're using, so it would also be worth checking to see if a driver update is available.

Closing this due to lack of activity from the reporter and no further information to investigate.

If you are the reporter and this bug is still a problem for you, or you are someone finding this issue and you believe this bug is still a problem and you have more information to share, please do not comment here and instead please open a new issue. You can reference this issue if you wish, but opening a new issue prevents confusion of accidentally linking two unrelated bugs and means that each issue can be handled in a clean process.
