We have a fix for that one. We are looking at having that in a next 5.3 patch. Thanks for your patience. In the meantime, if anyone wants to get the fix early, please integrate this change.
Do note that this is not a bug related to substrate in any way, so please next time I would kindly ask you to create a separate thread.
As a reminder: this thread is dedicated to feedback about Substrate. For instance: its workflow, parameterization, shading results, performance, avenue for research and improvements. If a problem you are looking at reproduces with substrate OFF, then it should not be posted in this thread.
I understand this is tempting, but we need to remain focused. Thank you all for understanding. We really value your feedback, enthusiasm and all the discussions here around Substrate!
