I have two thoughts:
1. In the Applications / Ubuntu Software / CompizConfig Settings manager I noticed this reply by one of the users of CompizConfig:
"Compiz has a lot of great features, from being able to draw directly on your desktop with your cursor to casting shadows under open applications. It has a number of issues, though.
Upon logging out and back in, the Y Bottom offset value keeps resetting to the default value of 48, when I specifically give it 0. I assumed that this was being reset by the Unity plugin, but it doesn't have a setting to correct this. I also notice that windows have trouble being focused when I click on them in window spread; it returns to the window I was viewing previously.
There are other issues, but most can be worked around."
I could be that the settings in CompizConfig are not stable and is the problem.
2. Can you run the following command to see if Deepin is the problem:
Code:
sudo deepin-feedback-cli
If you let us know what comes up maybe we can help further.
