            Bug ID: 500535
           Summary: Wayland: Translucent window artifacts remain on
                    wallpaper after minimizing inactive windows (NVIDIA
                    RTX 3070)
    Classification: Plasma
           Product: kwin
           Version: 6.3.1
          Platform: Arch Linux
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: kwin-bugs-n...@kde.org
          Reporter: 2knch...@gmail.com
  Target Milestone: ---

When window translucency is enabled in KDE Plasma, minimizing an inactive
(translucent) window causes the translucent image to remain embedded in the
wallpaper until either rebooting or running 'kwin_wayland --replace &'

Environment:
- KWin version: 6.3.1
- Distribution: Arch Linux
- Session type: Wayland
- GPU: NVIDIA RTX 3070
- NVIDIA driver: 570.86.16
- CPU: Ryzen 5800H

Steps to Reproduce:
1. Enable window translucency in KDE Plasma
2. Open any window and let it become inactive (translucent)
3. Minimize the translucent window
4. Observe that the translucent window image remains stuck on the wallpaper

Current Workaround:
Running 'kwin_wayland --replace &' temporarily fixes the issue until it occurs
again.

Configuration:
~/.config/kwinrc contents:
[Compositing]
AnimationSpeed=2
Backend=XRender
GLCore=true
GLPreferBufferSwap=n
HiddenPreviews=6
OpenGLIsUnsafe=false
WindowsBlockCompositing=false

[Effect-translucency]
ComboboxPopups=81
Dialogs=80
Inactive=81
IndividualMenuConfig=true
MenuOpacity=100
MoveResize=100

[Plugins]
minimizeanimationEnabled=false
translucencyEnabled=true

Additional Notes:
- Issue persists regardless of compositor backend (OpenGL/XRender)
- Issue persists with different translucency settings
- Issue persists with minimize animations disabled
