A .exr file loaded into renderdoc displays red streaks that are not present in other viewers

[expenses]

Description

I created a render using mitsuba3 and wanted to use to use renderdoc to view it. When I opened it I saw these streaks of red pixels to the right side:

I assumed that this was a mitsuba3-specific issue but I also tried a few other image viewers.

• https://viewer.openhdr.org/ displays the image without any streaks
• https://github.com/Tom94/tev displays the image without any streaks
• When I ran the file through a rust program that uses the image crate for loading .exr files, it didn't report any negative, NaN or infinite pixels.

I therefore I suspect that this is a problem with the renderdoc .exr loader.

Steps to reproduce

Download this file, unzip it and open the .exr in renderdoc:

pipe.exr.zip

Environment

• RenderDoc version: QRenderDoc v1.22 (387a9e5702756b321a90b3543d98579f3f3acd6d)
• Operating System: Arch Linux x86_64 on kernel 6.0.9-arch1-1
• Graphics API: N/A
• GPU: Intel TigerLake-LP GT2 [Iris Xe Graphics]

I'm not able to reproduce this unfortunately, the exr loads and displays correctly for me with no broken pixels. I tried on windows/NV, linux/AMD and linux/Intel with no luck. I also ran through valgrind just in case but it didn't spot any problems.

Are you able to reproduce this on any other system? On the system listed exactly what version of mesa are you using? I don't have an Arch system but I shouldn't think that matters.

Since you mention being on arch linux, are you running a build from renderdoc.org or built yourself from source? Distribution packages are not supported and can cause problems, so please try testing against either of those official sources.

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