Hi, thanks for the PR! as noted in #2935, we need to wait until the OpenEXR team has verified the fix; the fix has been merged but not yet released. |
I responded to your assessment in #2935. Please feel free to keep this open until OpenEXR verifies the fix, or to close it and wait for an OpenEXR release – whichever is more useful for you. |
