--- Comment #3 from Makoto <makoto.y...@gmail.com> --- I retested it a reproduced it right away. Here's the result of the command you asked, with the screens setup as they should be: kscreen-doctor -o | grep -E "Output|Geometry|Scale" Output: 1 DP-1 Geometry: 0,0 2752x1152 Scale: 1.25 Output: 2 DP-3 Geometry: 2752,36 1920x1080 Scale: 1 Output: 3 HDMI-A-1 Geometry: 0,0 2560x1440 Scale: 1 Out of curiosity, there's the result with the gap produced by the kscreen-doctor command: kscreen-doctor -o | grep -E "Output|Geometry|Scale" Output: 1 DP-1 Geometry: 0,0 2752x1152 Scale: 1.25 Output: 2 DP-3 Geometry: 3440,180 1920x1080 Scale: 1 Output: 3 HDMI-A-1 Geometry: 0,0 2560x1440 Scale: 1 And the same with 100% scaling on every monitors (no gap produced in that case): kscreen-doctor -o | grep -E "Output|Geometry|Scale" Output: 1 DP-1 Geometry: 0,0 3440x1440 Scale: 1 Output: 2 DP-3 Geometry: 3440,180 1920x1080 Scale: 1 Output: 3 HDMI-A-1 Geometry: 0,0 2560x1440 Scale: 1 I think something is off in the reported resolution of the DP-1 monitor that is 3440x1440 native and altered by setting more than 100% scaling. -- You are receiving this mail because: You are watching all bug changes.
