Niche case, but still. When I go into presentation mode (ctrl+shift+p) and exit (esc), okular crashes. It does this for one particular file, a presentation (pdf) and in it, there is an embedded webm video. Okular can play the videos both in presentation mode and without it. While I can't share the specific pdf right now, I can provide a MWE for how I produce the pdf that causes the crash: \documentclass{beamer} \usepackage[utf8]{inputenc} \usepackage{default} \usepackage{multimedia} \begin{document} \begin{frame} \movie[width=\textwidth, height=0.5625\textwidth, autostart, loop, poster]{}{graphics/video.webm} \end{frame} \end{document} I have tried with several videos and they all seem to produce the same result.

Someone will have to attach a pdf so people can try this, though it seems like one of those new "pulseaudio is all crashy" bugs we're having
You can use the one from https://bugs.kde.org/show_bug.cgi?id=376574 , for example.
