@Hanabishi It's still needed. kwin 5.21 has no option to disable vsync anymore and (on x11) limits fps on mixed refresh rate monitor setups (144Hz+60Hz) to the lowest one :/

On kwin-lowlatency it was easy to get 144fps on this setup. Now on upstream 5.21 my wobbly windows are visibly stuttering.

@Hanabishi In System Settings > Compositor > Latency, I chose Prefer lower latency.

Yeah, now with 5.21 update kwin already contains latency control option. And seems like this package is not needed anymore.

@kangalioo kwin-lowlatency does not support 5.20.90 or any of the upcoming Plasma 5.21 versions (at least not yet).

@longspear You can try to add the -DQT_X11_DEFINES_FOUND=1 option for cmake -B build

Holly molly, does this do wonders. I'm on no potato, yet I experience serious latency and smoothness improvements without any overhead- not even 1% CPU. Before, I had to turn off my compositor to get certain browsers to scroll smooth, despite kwin effects showing consistently good fps. But, now things are as smooth as the fps should imply. I hope wise KDE devs integrate this objectively better code into kwin someday.
