Hi folks, we're using pyvirtualdisplay for one of the flow, running container in k8s, and got intermittent failure `Failed to load and execute Flow's environment: StorageError("An error occurred while unpickling the flow:\n DisplayNameError('0.0')")`

One time, after flow registration, it works, another - no

Actually, we're initializing xvbf via pyvirtualdisplay later, when flow starts
But, when start fails, it fails while unpickling
Any ideas on how it could be solved (we don't want to start any default display when container starts, at that moment we don't know sizes which we'll need)
