Jitsi

,but it is a pain in the ass to selfhost with good performance.

You can take a look here as well:

One alternative that is not on the awesome selfhosted list is: https://edumeet.org/

But it is even more of a PAIN to selfhost it.

The button in OBS is called “screen capture” but when you press it, you can select “window” which results in only the window being captured, even though OBS says “screen”…

You can see it working in my screenshots. It captures only the window I selected (Dolphin, the file manager)

Should have made it bigger I guess.

1. Add screen capture

2. Your system will do a pop up to select screen, region or window

3. Here you can see it working with a window. If you don’t get the popup from 2, here is a button to force it

If that does not work for you, something is broken and if you want help you have to post details on OS, DE, OBS logs and system logs.

It is very hard to measure responsiveness (which is basically the only thing zen claims to be better at) without a lot of time investment and a high speed camera for frame analysis.

I guess a possible setup would be to run a multicore synthetic workload that takes most of the system resources and measuring the start time desktop applications.

But nobody has done it in a “scientific” way as far as I can see. Besides some hobbyist anecdotal observations:

zen and lts as fallback

iirc zen has a scheduler that is supposed to be better for single user multitask desktop situations, while the regular kernel scheduler is better for server workloads.
