SUMMARY 

KWin Wayland reports "Invalid framebuffer status: 'GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT'", causing graphical issues.

STEPS TO REPRODUCE

Boot the system and log into KDE Plasma with Wayland.
I use the system normally, especially with graphically intensive applications.

OBSERVED RESULT 

Multiple log entries showing "kwin_scene_opengl: Invalid framebuffer status: 'GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT'".

EXPECTED RESULT 

No such errors should occur, and the desktop environment should function without graphical issues.

Please attach the full kwin log (journalctl --user-unit plasma-kwin_wayland --boot 0) after you see the graphical issues.

Also, what do those issues look like?

Thank you for your reply. I have attached the full KWin log as requested, generated using the command journalctl --user-unit plasma-kwin_wayland --boot 0 after observing the graphical issues. The file is named kwin_log.txt.

Regarding the graphical issues, they typically manifest as flickering or black screens when interacting with certain applications, especially those that are graphically intensive (e.g., games or 3D rendering software). Sometimes, the entire desktop environment becomes unresponsive for a few seconds, and I notice visual artifacts like distorted windows or missing UI elements. These issues occur intermittently, often after a period of normal usage, and are more frequent when running applications that rely heavily on OpenGL.

Let me know if you need any additional information or if there’s anything else I can do to help diagnose this issue.
