Version: 6.2.0.0.alpha1+ Build ID: cd9aa5bc508244082b4baf4a3094875bf2c6f992 CPU threads: 4; OS: Linux 4.18; UI render: default; VCL: kde5; Locale: en-GB (en_GB.UTF-8); Calc: threaded This is specific to the qt5/kde5 VCL plugins. It works e.g. with gtk3. Steps to reproduce: 1) create a new presentation consisting of just one slide in Impress 2) start presentation mode, e.g. by pressing F5 (side note: until bug 120451 is fixed, you'll need two screens, otherwise a crash 3) left click to actually start the presentation (side note: this is necessary due tobug 119718) 4) make the "presentation window" the active one, not the one with presenter console 5) click to advance (Text "Click to exit presentation..." appears, since slideshow is over) 6) click again (or press Esc) Result: LibreOffice crashes
