Created attachment 161474 [details] Example of one slide with vertical and one with horizontal displacement Hi, I have some impress presentations, that were working well with libreoffice under Ubuntu 18.04 (with ubuntu package, with AppImage and with snap). After upgrading to Ubuntu 20.04 some (but not all) slides (see example file attached) became unreadable because horizontal or vertical kerning / positioning is broken and characters get printed too close and over it's left or upper neighbor. The bug exists with - original ubuntu packages (6.4.3) - original libreoffice 6.4.1 AppImage (same appimage working well on 18.04, but not on 20.04) But it does not occur on the snap version 6.4.3.2. That is working well, but has not access to all fonts installed on the system (maybe that's what on the other hand prevents the problem). Although I do consider this rather as an Ubuntu problem, I think you should know about it.
I made some progress in debugging. Under Lubuntu 20.04 the environment comes with the variable SAL_USE_VCLPLUGIN=qt5 set. When unsetting it, the bug does not occur.
Plain Qt5 without Cairo rendering is not yet mature, see https://bugs.launchpad.net/ubuntu/+source/lubuntu-meta/+bug/1895216 Maybe try with a master build of 7.1 as there were some fixes recently.
