--- Comment #7 from Toby Fox <toby...@gmail.com> --- I'm having the same issue but with slight variation, not sure if the exact same bug: - Entire UI (kwin? plasma?) freezes for anywhere from 100ms to 1000ms whenever any notification appears - Audio does *not* freeze. Mouse cursor also doesn't freeze, still moves smoothly - I have a dual integrated Intel GPU + NVIDIA GPU (using bbswitch) and my NVIDIA GPU is switched off, so the issue isn't unique to NVIDIA drivers I can reproduce as follows: 1. Open konsole and fill it with enough content such that you can scroll 2. While scrolling up and down with mouse/trackpad, run `notify-send foo` 3. Scrolling freezes for half second when notification appears I tried both triple-buffering and the usleep environment variables for kwin, but no dice. Also tried setting "force lowest latency" in compositor settings, didn't seem to make a difference. Overlays from changing monitor brightness and volume cause the same stutter. It happens only when the overlay first appears: once it's visible I can continue changing the volume without further stutter, and notifications/overlays disappearing do not cause stutter.
