Manjaro Deepin: Window Effects can no longer be enabled

I can't enable the Window effects anymore. My CPU is a AMD A10-9700 RADEON R7 and I have the open source graphic driver installed.

The error message is simple: Error activating window effects.

All I have done so far is:

> deepin-wm --replace

That didn't change anything, though. Can anyone point me in a direction where to look for the causes and a possible solution? Google didn't help much.

If you are using deepin-wm try deepin-kwin or vice versa.

Actually try this, open ~/.config/kwinrc
Check if OpenGLIsUnsafe=true, set it to false if it is set to true.
