I'm using two displays which have same resolutions. I clone these display output. Right after login from sddm, a screen has hidden area right to the shown area, which can be scrolled in using mouse. This is not desirable behavior. The screen must be exactly what is shown. I can fix this problem temporarily by changing display setting (once cascading two displays, then back to cloning). My video driver is nVidia proprietary. Reproducible: Always Steps to Reproduce: 1. Login to KDE from SDDM (I don't know if this happens using other DM) 2. Move the mouse cursor to the right edge. 3. You will see the screen scrolls to right and see hidden area which should not exist. Actual Results: The screen scrolls to right and see hidden area which should not exist. Expected Results: The screen does not have any hidden area.
