How to make a click go through to a button in an inactive window?

Hi everyone,

I have a problem with the Unity Engine Editor on Manjaro KDE Plasma with X11. I have three Unity windows, one for each of my three monitors. When one of them is active and I want to click a button in another window, I need to click it twice, once to activate the window and once to actually click the button. Shouldn’t the click go through the first time?

I checked the window manager settings and found “actions for inactive inner window”, which has “activate, to front and talk to with click” (not sure what it’s exactly called in English). This sounds correct to me since the other options are just activate or just activate and to front. I’m not sure what an inner window is though.

The general rule for window activation is “with click”, which is what I want, I just want that click to go through immediately. Is that possible?

Here’s a screenshot of how Unity looks so you can possibly figure out how its windows are composed. And here’s my system info.

Operating System: Manjaro Linux 
KDE Plasma Version: 6.7.4
KDE Frameworks Version: 6.28.0
Qt Version: 6.11.1
Kernel Version: 7.1.8-1-MANJARO (64-bit)
Graphics Platform: X11
Processors: 12 × AMD Ryzen 5 3600 6-Core Processor
Memory: 32 GiB of RAM (31.3 GiB usable)
Graphics Processor: AMD Radeon RX 5700
Manufacturer: Micro-Star International Co., Ltd.
Product Name: MS-7B89
System Version: 1.0

If you want the click to go through you need activate window on mouse hover.

The logic of the window manager - says you cannot have both.

Thanks! Is there a way to change the activation behaviour per application, virtual desktop or anything else or does it have to be global?

The setting applies to the entire desktop. One cannot set this on an application basis.

Alright, thank you.
