Description throwtuna 2025-12-08 07:21:23 UTC 
Summary: On Fedora 43 (Rawhide), triggering the Overview effect (via hot corner) results in a blank grey screen where window thumbnails should be. Text labels, icons, and the search bar render correctly, but the window content textures are missing.

The journal shows GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT errors from kwin_wayland.

Software/OS Versions: Operating System: Fedora 43 (Rawhide)
KDE Plasma Version: (Latest Rawhide build)
KWin Version: (Latest Rawhide build)
Windowing System: Wayland
Graphics Driver: NVIDIA 580.95.05 (Open Kernel Module)
GPU: NVIDIA GeForce RTX 5060

Steps to Reproduce:
Log into a Plasma Wayland session.
Open several windows.
Trigger the "Overview" effect (e.g., via Hot Corner).

Observed Results: 
The Overview activates, but window previews are blank/grey rectangles. Only the application icon and window title text are visible.

Relevant Logs (journalctl):
Dec 08 06:56:18 UNKNOWN kwin_wayland[11850]: Invalid framebuffer status:  "GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT"

Workaround: The issue was resolved by clearing the shader caches and restarting the session: rm -rf ~/.cache/qtshadercache* rm -rf ~/.cache/mesa_shader_cache rm -rf ~/.cache/nvidia/GLCache
