erreur lors de la construction : kwin-lowlatency

Tried with 5.20.4 too, same.

I have no issue running kwin 5.21 @240hz with a dual monitor setup, secondary being 75hz on AMDGPU. The trick is to enable TearFree and then kwin will sync with the primary monitor. If you need to disable vsync, use the environment variables mentioned here

I'm in the same boat as Kiwii... I have a 144hz primary monitor plus a few 60hz. Everything was super smooth and fast on kwin-lowlatency and the compositor ran at 144fps. Vanilla kwin 5.21 feels like a dumpster fire in comparison... it's stuck at 60fps and choppy and stuttering on a GTX 1080 Ti. I tried kwinft with similar results.

@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.

Hanabishi commented on 2021-02-17 16:13

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
