--- Comment #4 from GHPS <kde-softw...@guido-schroeder.de> --- Update: The bug is still present even in the latest Kubuntu Neon with KDE 5.8.3 (neon-useredition-20161114-0947-amd64). But I spend some time on further testing. After tweaking various combinations of resolution, desktop background and visible widgets I came up with a temporal fix for the black bar problem - and an idea what causes the problem. If on both screens the background is set to “Simple Color” and the resolution on the second screen is lowered to 1920 and re-set to 2560x1080 then the desktop background is flawless. Even the Hunyango desktop background works fine. Unfortunately the black bar immediately reappears when a widget is dragged-and-dropped on this desktop. At least in Neon this trick didn’t work when a desktop background pattern was enabled on the first screen. My guess is that the desktop background and/or the widget subsystem corrupt parts of the buffer memory. -- You are receiving this mail because: You are watching all bug changes.
