I've been testing kernel 6.8.0-38 (from proposed) and while it's not fixing the problem completely, at least on my hardware it is somewhat better. The flickering happens once in 2-3 days and is very brief (~1s).
I can't recommend using kernel 6.8.0-38 since it shows unhealthy amount of warnings related to iommu.
But assuming kernel team fixes the iommu issues, we might have a major relief with the following release.
