texture warnings on save/ load state
We have an unacceptable number of texture warnings when saving then loading state. Here is how to replicate:
- nightly 5.9.1-1808-gdb1698b0, MacOS, builtin server.
- Reset to Default Settings
- File/ Open/ Examples/ can.exo. Apply.
- File/ Save State.
- Reset Session.
- File Load State. We get the following, maybe 100 or so times:

Really should be fixed in 5.10.
