Transparency in compton does not work

[RantSomeWhere]

Starting compton as superuser with the -b flag fixes it. It still throws a bunch of errors, but at least transparency works. I'll close this issue.

Looks like vsync = "drm"; doesn't work properly for you.
I'm not sure what will work for you but try changing values of backend and vsync in ~/.config/compton.conf. Here's the guide: https://github.com/chjj/compton/wiki/vsync-guide

I've also tested it right now and the driver you use makes a difference
I have an NVIDIA graphics card, a GT520M so I use nvidia 390, and here's my observation:

• backend = "xrender"; works on nouveau, but not on nvidia-390xx
• backend = "glx"; works on nvidia-390xx, but on nouveau the transparent windows will become pink (much worse than not working at all)
