Not in my '04 330Ci, but I had a
1992 LS400 and the same situation was endemic to this car. Just a wearing out of the product. Varies with temperature and although it is still usable, it is irritating.
Only remedy is to replace it.
How expensive is your version?
Pick your model
Yes my Subie has that. It's from the heat
And it's very distracting.

Interesting follow up. This just points out that
it would be really easy as a modern and high tech BMW ages it will easily nudge into the realm of where it would easily take an investment much larger than the book value of the car just to keep it working normally. Frightening thought if you have a really long term operating goal in mind. Eventually the cost of a few items such as your mirror could be more than a replacement car costs.
