Hi.

I've tried installing the kwin-lowlatency, but keep running into this issue

I tried reinstalling all packages, reboot, but it keeps stopping when building.

kwin-lowlatency isn't updated to Plasma 5.21 yet. This means it cannot be installed on a System running Plasma 5.21 or newer at the moment. However, "stock" kwin should be a lot better from Plasma 5.21 onwards. If performance isn't on par with kwin-lowlatency for you, try to set you CPU frequency scaling governor to "performance": https://wiki.archlinux.org/index.php/CPU_frequency_scaling#Scaling_governors If you need stuff like fullscreen unredirection, you're currently out of luck unfortunately, if you absolutely depend on this feature, use kwin-lowlatency forks or a static release distribution like Ubuntu or openSUSE Leap.

Alright. The reason I wanted to install kwin lowlatency was because high refresh rate with multiple monitor setup doesn't work properly unless I disable composing. I was curious if kwin lowlatency would solve this.

I know you can set "MaxFPS=144" in kwin config, but this was not recommended to as I've heard. The devs at KDE told people not to do this as it cause "strange" issues and so on

Hello! I have updated KWin-lowlatency to 5.23.3 now. Try building it.

Confirmed that it works perfectly.

Marking as done hoping that KWin-lowlatency 5.22/5.23 builds correctly.
