Bug ID: 483052
Summary: Plasma 6 - stuttering, redrawing previous frames? I
have examples of video stuttering and typing
stuttering.
Classification: Plasma
Product: kwin
Version: 6.0.1
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: cru...@gmail.com
Target Milestone: ---
SUMMARY
Apologies, I'm not an expert in graphics/compositing/drawing, so please let me
know if I can provide any other info.
Using Plasma 6 (which I understand is wayland), stutters and redraws previous
frames. For example, in Guake, when typing, characters will appear, but
sometimes the most recent character would disappear (reverting back to a state
before the keypress?). Or when backspacing, the characters will disappear, but
occasionally reappear. I tried to capture a video (with my cell phone - I
didn't trust screen capture to "see" compositing glitches). The HTML rendering
in Google Chrome was also glitchy. Reddit had elements
flickering/disappearing/reappearing. I also captured stuttering on a YouTube
video.
I've have example videos of YouTube and typing stuttering in Google Chrome, but
issues affect much more than just Chrome: my Jetbrains IDEs, Guake, etc, etc.

STEPS TO REPRODUCE
1. Use Plasma 6? No specific steps. Stuttering seems to be happening across
multiple applications.
