If possible I would also like to downgrade to version 7.2.2
It's not possible. We only support the latest official version, so we only distribute the latest official version.
I had the same issue and updated today to version 8.1
It is common for users to believe they have "the same problem", without reporting their real situation, and that they are different things, so open a new topic, with as much information as possible, about hardware, about what you've already tried, etc, because this topic is from another version and may not be directly related as it seems.
