Manjaro is choppy / lagging when opening or moving / resizing windows

[MarioDesigns]

Hi! I’m loving Manjaro so far however I’m noticing that it’s quite choppy when I open or resize a window.

I’m using KDE Plasma and the proprietary NVIDIA driver.

See this as an example and something you could try:

Hello, Since is about KDE Plasma and Nvidia GPU, maybe you have to do what i do. Open in Kate the /etc/X11/mhwd.d/nvidia.conf and in the Section "Device" replace the line Option "NoLogo" "1" with: Option "TripleBuffer" "On" Option "ConnectToAcpid" "Off" Option "metamodes" "nvidia-auto-select +0+0 {ForceFullCompositionPipeline = On} Save it then create the file kwin.sh to use the triplebuffer, from terminal run: echo "export KWIN_TRIPLE_BUFFER=1" | sudo tee /et…
