Hello!
In both bathroom windows, as well as in the (identical) window of the separate toilet, condensation forms almost daily during winter. As a non-expert, I’m not quite sure why this happens or if there is anything I can do about it. Especially in the toilet room, where there is no significant humidity, I don’t understand where the moisture is coming from at all. At least in there, this shouldn’t really be happening, right?
Thanks for any help, advice, or sympathy 😉

Well, in a poorly insulated house from the 1960s, this doesn’t seem particularly extreme to me... but today I’m ventilating every hour and have tightened the mushroom locking pins on one window. Let’s see how the windows look tomorrow.
By the way: the guest toilet (one floor below) has the same window. However, I have never found even a drop of moisture there (although it actually has the same conditions as the equally sized toilet upstairs).

So, I waited two nights. There is noticeably less water visible in the window with the engaged mushroom cams (espagnolette locks), but some moisture is still present. By ventilating regularly, I managed to reduce the room humidity to below 50%.
I’m still not entirely sure how the water is getting in there. The window now seals really tightly. Especially since, as mentioned, the same window in the guest bathroom does not show a single drop. Other older windows in the house also have no moisture in the frame.
Thanks for your advice!

From my point of view, this is just a symptom – in your place, it is either damp, poorly ventilated, or both. A few drops on the rubber seal are not the problem – I would be more worried about waking up in a stalactite cave someday...
