--- Comment #10 from Ed <[email protected]> --- I found the root cause, and this can be closed as a local hardware/display-topology issue rather than a KWin bug. One of my monitors was connected through an HDMI source-switching / splitter-type device so I could switch between machines. That same display topology also involved another direct cable/source path, which means the GPU/display stack was likely seeing confusing or unstable monitor/source information during cold boot. After simplifying the monitor cabling and removing that switching path from the affected setup, I have now tested multiple cold boots over the last several days. The display layout initializes correctly, and the issue no longer reproduces. I have also switched from X11 to Wayland on Fedora 44, and Wayland is now working properly with this corrected cabling setup. I apologize for the noise, and I sincerely appreciate the time spent looking at this — especially the distinction between this report and the logout/shutdown teardown issue, and the request to test Wayland. That helped me narrow this down. Thank you to Nate, Vlad, Xaver, David, and everyone else copied here. Please close this as a local hardware/configuration issue / not a KWin bug. -- You are receiving this mail because: You are watching all bug changes.
