picom VS xclickroot

What distro? My pref is for Jonaburg's fork. Ibhagwan is out of date. Pijulius more so. Yshui doesn't have animation.

This configuration uses Qtile extra package and one of my favourite picom fork for minimalistic look with rounded-corners

As others have said, Awesome doesn't ship with a compositor so you need one yourself. My choice is jonaburg's picom fork for the extra included features, but regular picom will do the job.

Install jonaburg picom https://github.com/jonaburg/picom

picom-jonaburg has rounded corners and animations. Window gaps are controlled by your window manager, compositors can't interact with them.

Offtopic: I know you didn't ask this, but I just saw the fork you are using was updated the last time in 2020: https://github.com/jonaburg/picom/tags . The current version of the original https://github.com/yshui/picom/releases got updated this year (2 years more development!). Unless you are using features that is only available in that fork, I would try the mainline, which also got some of these features too, in example support for rounding corners. So maybe this newer version works better.

I am using Qtile (on a Laptop running Ubuntu 20.04), with jonaburg-picom, which is blurring my Qtile bar since some parts of it are configured to be transparent. How do I get rid of that blur, can someone help me with this?

This is how I do it with awesomeWM on EndeavourOS. Maybe this will help you. I'm using picom-jonaburg-git.

I was trying to bind a few commands to my mouse buttons/scroll wheel via xclickroot and later via sxhkd and I ran into a strange issue where I couldn't scroll via the scroll wheel in GTK applications. The applications appeared to respond to clicks, but the scroll wheel did nothing. Also, the cursor that was displayed was not always correct (e.g. sometimes it wouldn't show the hand that indicates an item is clickable when it ordinarily would). When I tried sxhkd, I made sure to replay mouse events for clients, but to no avail.

There are so many ways you can fit pieces together and don't have to worry about them changing on you, if you don't want. One thing I have been thinking about doing is ricing a setup script for Xen and/or KVM (I have to say, I like KVM more, but Xen is definitely easier to get passthrough working with,) and I finally found a right-click menu someone wrote which is just amazing: xmenu and another program written to work with any WM not just DWM xclickroot.
