@yshui Not problem, thanks for you help, my knowledge in C/git is limited, but with this changes I have been able to unbreak the build and use picom v11+ without problems with amdgpu on OpenBSD, and if the changes arrive and are maintained upstream they will generate fewer problems to compile and maintain the project on OpenBSD.
