--- Comment #3 from Tom Warnke <tom.war...@kolabnow.com> --- Hi Sebastian, I can drag windows onto the non-working monitor. Last week the part of them that was on the non-working monitor became invisible. But they were there, and I could activate them by clicking at their invisible part. Today I installed some updates from the Frameworks 5 repository (http://download.opensuse.org/repositories/KDE:/Frameworks5/openSUSE_Leap_42.1/) and a kernel update (4.7.4 -> 4.7.5), and now windows and menus on the vertical screen are visible. However, the screen is still very slow. I can literally see how it repaints the screen from top to bottom when I drag windows across it. Also the background when removing a window is not repainted correctly, leaving black areas instead. Animations/desktop effects are slow on other screens as well as long as one screen is vertical. Thanks for looking into this, Tom P.S.: I will be traveling for the rest of the week and probably not be able to do further tests until next week. -- You are receiving this mail because: You are watching all bug changes.
