I can replicate this setup (with the screens' scale factors swapped, but that won't make a difference) and I can reproduce the issue with current git master. Still reproducible with 5.27.4 This problem is caused by the position of outputs being remembered separately from mode and scale. As a possible solution, we could maybe store the relationship between outputs in the output config, instead of only an absolute position |
Created attachment 145907 [details] KWin support information: Step 1 STEPS TO REPRODUCE 1. 4k@200% DP monitor (primary, left) + FullHD@100% HDMI, adjacent to each other in KScreen 2. Changed scaling of DP to 100% 3. Unplugged the HDMI monitor 4. Changed scaling of DP to 200% 5. Plugged back in the HDMI monitor OBSERVED RESULT Logically the two monitors are now very far apart and all windows and the mouse are confined to the primary monitor, i.e. cannot be moved to the other screen SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Neon Testing KDE Plasma Version: 5.23.90 KDE Frameworks Version: 5.91.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION Wayland
