--- Comment #7 from Harald Sitter <sit...@kde.org> --- Yes. That is entirely consistent with what we see in the two bug reports. What goes on in your screenshot is that the KCM thinks you are at a scale >1 so it takes the the actual resolution of your left hand screen and divides it by the scale. This then is the "logical" resolution that is smaller than your actual resolution. Say your left screen is 15x15 and has 1.5 scale. The logical size is 10x10. And that is the basis for the layout in the KCM preview. That is why it looks smart there (it behaves as though you were still in wayland). Kscreen then has the config first screen at point 0,0 with width=10 and height=10. second screen at point 11,11 width=5 and height=5 (random example values). Plasmashell (or KWin, unsure about responsibilities) on the other hand knows that you are on x11 and so wayland scale has no impact. The first desktop consequently gets rendered at 0,0 with width=15 and height=15 (these are the unscaled values!). Then it renders the second screen. KScreen says the second screen is at position 11,11. Plasma draws the desktop at that location with a width=5 and height=5. The second screen is now drawn on your first screen because the KScreen position was wrong. Hope that makes some sense. Essentially the KCM pretends you have wayland scaling, but you really don't so the positioning between KCM (scaled) and real world (not scaled) are out of sync and that results in things getting placed and incorrect locations. -- You are receiving this mail because: You are watching all bug changes.
