USD 24.08 + OCIO 2.3, HdxColorCorrectionTask error in usdview with storm on linux

[pberto]

Description of Issue

Steps to Reproduce

1. Make a build of USD 24.08 build with OCIO 2.3 on Linux
2. OCIO variable is set, usdview is launched. Use soem color profiles like the default SPI ones.
3. when switching the various color profiles in usdview UI, we see totally borked colors in the storm viewport, along with these errors on the cli:

ERROR: Usdview encountered an error while rendering.
        Error in 'pxr_v2408__pxrReserved__::HdxColorCorrectionTask::_CreateOpenColorIOShaderCode' at line 562 in file /pxr/imaging/hdx/colorCorrectionTask.cpp : 'Failed verification: ' !texInfo.texName.empty() && !texInfo.samplerName.empty() ''

Any pointers?

Can you at least please confirm if on linux you are still building with python39 and with ocio 2.1.3?

[jesschimein]

Yes, that’s right. Python and OCIO are both part of the VFX platform and we’re currently on VFX platform 2022.
