  1. I'm using picom on Ubuntu and "picom --version" says "v9" and "apt policy picom" shows that I've version "9-1" installed. For this version, I run picom like this: picom --config /dev/null --log-file /dev/null --shadow -o 0.20 -r 8 -l -8 -t -8 --corner-radius 4 --backend glx --glx-no-stencil --glx-no-rebind-pixmap --no-use-damage --xrender-sync-fence --vsync --shadow-exclude '_GTK_FRAME_EXTENTS@:c' --shadow-exclude "name ?= 'Thunderbird' && (window_type = 'utility' || window_type = 'popup_menu')" --shadow-exclude "_NET_WM_STATE:a = '_NET_WM_STATE_ABOVE' && _NET_WM_WINDOW_TYPE:a = '_NET_WM_WINDOW_TYPE_MENU'" --shadow-exclude "WM_CLASS:s = 'xfwm4-wireframe'" --shadow-exclude '! class_g && ! class_i && ! _NET_WM_WINDOW_TYPE:a' --no-fading-openclose --unredir-if-possible --unredir-if-possible-delay 50 > /dev/null 2>&1 & Note that the command line is long only because I don't use any config files so this command line defines everything. I'm running this on GTX 1060 3 GB so this should be easily fast enough on any Nvidia hardware. The shadow-exclude rules workaround broken shadows for Thunderbird, Firefox, Chrome and XFCE.

  2. If you're using Intel integrated graphics, you typically want xrender backend because it requires less processing power from your GPU and intel integrated graphics is not the fastest thing in the town.
