Recently I installed the Deepin and I had a problem with the touchpad. 

When i touch with two fingers, the desired action fires as it should (it opening context menu, same as with right mouse key).

But right after that some kind of system gesture is triggered. The last system notification seems to be playing and this closes the context menu. Because of this, it is impossible to use the touchpad normally.

 I tried to check the system configuration file, but i unable to find the proper setting.
