Xpresent will not help in having transparent titlebars - it's about either "vsync events" - ie getting some event on a refresh on a given window/screen for timing (probably really useful for determining animation timing) or displaying a final rendered pixmap to a given target window and some fences/timing etc. As per my original mail the transparency is a matter of rendering, so I suspect the xpresent renderer in picom is a bit of red herring here in terms of naming. As I said - it's not my project so I can't comment beyond that. -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- Carsten Haitzler - ras...@rasterman.com
