Yes this is a known issue that does occur in some situations with certain systems, video drivers, or software applications.
If updating video drivers does not resolve the issue, you may simply need to use your current workaround.
Thank you for the fast response. I will try updating the video drivers.
If updating the video driver didn't provide any resolution, you may want to create a user account specifically for recording.
Set the account to only have a single primary monitor, or set multiple monitors to mirroring.
This will allow you to login for recordings, have the video preferences set to a specific repeatable resolution, and the recording will have a consistent resolution for each file you generate.
