With TraditionalOK theme I have following results:
- using unmodified sample config:
- using modified
/usr/bin/marco-xrender
script with your parameters (inactive-opacity = 0.8
,frame-opacity = 0.7
) :
I think, you have to apply other parameters from the script to your config. The only artifact I see is the non-transparent area in titlebar.
MATE Tweak uses modal window, the other ones are resizable. I believe this frame artifact is related to Marco: Backport invisible resize borders by vkareh · Pull Request #503 · mate-desktop/marco · GitHub .
Xpresent is a part of Xorg: xorg / lib / libXpresent · GitLab . It's simply a library used by Marco in compositing mode: marco/src/compositor at master · mate-desktop/marco · GitHub, you may ask Marco developers.
Marco/picom integration scripts are coming from MATE Tweak: GitHub - ubuntu-mate/mate-tweak: Tweak tool for the MATE Desktop .
