@Flash0ver I think we need a way to reproduce this in order to be able to do anything about it. Have you been able to reproduce the issue? If not, let's add a 'Needs Reproduction' label and lower the priority until we get some further clues/feedback from the customer.

No ... not yet ... we are currently working with the customer on a reproduction.
