Description: I tried to show the presenter console on one display and the presentation on an other display under opensuse 15.1 with libreoffice 6.2.7.1. This results in only showing presenter console. The presentation will be displayed in the background of the presenter console. So the presentation is invisible. I can change between both views with Alt-Tab. I tried several Versions of libreoffice to find out which version is affected. All Versions from 6.2.0 on are affected. Steps to Reproduce: 1. Use computer with two displays 2. Use opensuse Leap 15.1 with plasma desktop or icewm desktop 3. activate presenter console in libreoffice 4. open presentation 5. start presentation (F5) Actual Results: 1. Presenter console shows up on presenter (first) display. 2. Presentation shows is invisible and located behind presenter console on presenter (first) display. 3. presentation (second) display shows normal background wallpaper Expected Results: 1. Presenter console shows up on presenter (first) display. 2. Presentation shows on presentation (second) display. Reproducible: Always User Profile Reset: Yes OpenGL enabled: Yes Additional Info: Version: 6.2.7.1 Build-ID: 20(Build:1) CPU-Threads: 12; BS: Linux 4.12; UI-Render: Standard; VCL: kde5; Gebietsschema: de-DE (de_DE.UTF-8); UI-Sprache: de-DE Calc: threaded
Could confirm the buggy behaviour. Have tested with a simple impress-file and LO 6.3.3.2., VCL:kde5. Slide show settings have been set to "Presentation display: Auto External(Display 2) - but nothing could be seen there.
I understand from report and confirmation that this is kde5. Please explain why this is a regression, with which version it worked.

Works will all versions up to LO 6.1, fails first with LO 6.2 on the same OpenSUSE system. Both tests were made with OpenSUSE and KDE. There has been kde4 in LO 6.0, could also be LO 6.1. Also gtk has been changed from 6.1 to 6.2, but we haven't tested with gtk.
Other people in German opensuse-user-list tested this one. Seem to work with gtk3, so a special kde5-bug.
What Qt version do you have? Is this with X11 or Wayland? There is a bug in Qt versions < 5.10 that cause this issue, s. bug 119719 for details; and the problem still seems to be there with newer Qt versions on Wayland, s. bug 128214, so if any of the two conditions are met, there's probably little we can do from LibreOffice side...

This means that you're affected by the Qt bug as described in bug 119719. The problem should go away once a newer Qt version is available/installed. As a workaround until then, you can start LibreOffice with the environment variable SAL_USE_VCLPLUGIN=gtk3 or SAL_USE_VCLPLUGIN=gtk3_kde5 set to force using the gtk3 or gtk3_kde5 VCL plugin -- or manually arrange the two windows as needed. *** This bug has been marked as a duplicate of bug 119719 ***
