Sadly, it was very bad. I tried it about five years ago on a Pi 4. In less than a year, the Pi crashed five or more times. Once it was due to a faulty SD card, and on several occasions it was due to other software on the Pi crashing. Each time, the internet went down, which made my family unhappy, especially when I was not at home and could not fix it.

I also saw little benefit as I already block ads on all my devices, and my smart home stuff has no internet access at router level.

I haven’t tried it since. Should I try again now with redundancy? What are the benefits?

Thank you for your answer. I should have mentioned that I had already tried that.

Yes, this disables window snapping to screen borders, but not the strange grid behaviour when moving windows with the Shift key pressed.

Do you experience the same behaviour on your machine?
