@diddly-chops, it certainly sounds like you have a different bug to 92599. I assume you have also tried setting Detect Refresh Rate = OFF and Refresh Rate to match your monitor (or double thereof)?
If that still doesn't work then you certainly have a different bug. However because this bug was logged by someone other than yourself, we shouldn't unduplicate this bug just yet.
Please log a new bug of your own with as much detail as possible so hopefully it can be classified and dealt with more accurately.
