Deepin is one of the best distros without any doubt, but like everything, sometimes unexpected things happen and do not know how to solve them. It's very frustrating when you do not know what has happened in our system that no longer works as as we had, it is the case that for some strange reason transparencies no longer work; and yes, a way to solve it is creating another user, but then that means that something wrong is in shaping our own, so to solve this minor inconvenience must do the following.
1. Enter our personal folder and press the keys Ctrl + H to see hidden files and folders, they will be a starting point.
2. We seek and open the folder .config and once inside look for the filekwinrc
3. Rename the file mentioned above; I can think of puttingkwinrc.respaldofor anything that might happen.
Four. We can restart Deepin or simply log out and back in.
With this we should be able to re-activate and / or deactivate the Effects Window.
We hope you find it useful, any questions leave us a comment.
