Bug ID: 507943
Summary: Desktop switching animation stutters when a browser is
open, especially during video playback
Classification: I don't know
Product: kde
Version First unspecified
Reported In:
Platform: Bazzite
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: general
Assignee: unassigned-bugs at kde.org
Reporter: rafacolucci at gmail.com
Target Milestone: ---
STEPS TO REPRODUCE
Open a web browser (e.g., Firefox or Chromium-based) on Desktop 1.
(Optional) Start playing a video (e.g., YouTube).
Switch to Desktop 2 using the keyboard shortcut Ctrl + Meta + Right Arrow.
OBSERVED RESULT
The desktop switch animation stutters. The issue is more noticeable when a
video is playing in the browser. It does not occur with other types of
applications.
EXPECTED RESULT
Smooth desktop switching animation, regardless of which application is open or
what it's doing.

KDE Plasma Version: 6.4.3

The compositor is enabled and using default settings.
The issue is specific to KDE and does not occur in other desktop
environments like GNOME or XFCE.
The stutter seems related to hardware-accelerated content in browsers,
possibly a rendering or synchronization issue.
