Bug ID: 445088 Summary: Dual monitor setup: Program window display gets mashed up when small old monitor is configured left (aside new higher dpi monitor) Product: kwin Version: 5.18.7 Platform: openSUSE RPMs OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: multi-screen Assignee: kwin-bugs-n...@kde.org Reporter: t...@arcor.de Target Milestone: --- Created attachment 143288 --> https://bugs.kde.org/attachment.cgi?id=143288&action=edit Screenshot SUMMARY The program window display of some programs (VLC at video playback, Kontact, LibreOffice) gets mashed up when small old monitor is configured left (aside new higher dpi monitor). (Settings-Display and monitor). When the old small monitor is configured right aside the new one, everything works fine. STEPS TO REPRODUCE 1. Open Settings - Display and monitor 2. Move the box representing the old monitor to the left 3. Start Kontact, VLC player (video playback) or LibreOffice --> program window display will be mashed up. :( 4. Move the box representing the old monitor to the right (no restart required) 5. Start Kontact, VLC player or LibreOffice again --> everything works fine :) See screenshots. Workaround: a) Libre Office: remove libreoffice-qt5 and libreoffice-gtk2 package, install libreoffice-gtk3 package instead (?!) b) VLC: use custom skin ("avs 95 beta") Hardware: Main display: Eizo 27" 2560 x 1440 (144ish-dpi) 2nd display: Acer 19" 1280x1024 Geforce GT 610 Software: OpenSuse Leap 15.3 KDE 5.18 LTS NVIDIA 390.144-lp153.31.1 graphics driver (closed source) libqt* 5.12.7* KDE Framework: 5.76 -- You are receiving this mail because: You are watching all bug changes.
