Hi - first of all, thanks for all replies.
I had an authorised dealer to do the oil change on my old bike, and I always trusted it to have been done correctly, so I never checked. As this is the first MC oil change I do by myself, I am watching out for all possible issues and asking when I am in any doubt.
I was thinking that it is not good to have bubbles in the oil, so I was prepared to do a second oil and filter change. Good that I didn't do it, because I would end up with the same "issue". I hear from others that bubbles in oil is normal after a ride - and the harder the ride, the more bubbles. The oil will be splashed around gearbox and stuff, and it is impossible not to get aired. After 3-5 minutes of restling, the bubbles should settle, and then you can check the oil for looking weird.
Try it yourself on the next ride.
Yes, the oil was overfilled slightly. But just slightly. 2-3 mm over the max setting. The engine runs perfect, starts perfect, makes no noise or white smoke. Temperature is normal. I expect nothing to be wrong. I was told to check the overflow hose for the airfilter for any oil. Where do I find that on the 1050?
Also curious to see if the spark plugs are wet, but... I do not think so. I am not planning to check that right away.
I could smell some engine oil after the oil change, but I imagine that is it from excess oil outside the engine.
