SUMMARY Upon resume from sleep, Ocuklar shows black space, not the slide. STEPS TO REPRODUCE 1. Open PDF with Okular. 2. Suspend PC - possibly only when Okular is in full-screen mode. 3. Resume PC. OBSERVED RESULT Black screen with an Okular menu popping-up when I mouse to the top of the screen. EXPECTED RESULT The slide seen pre-suspend should be visible. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Mint 19 Cinnamon x64. Qt Version: unknown. ADDITIONAL INFORMATION This problem may owe to Mint or Ubuntu or even the kernel. My kernel is a 4.19 one.
When I try to suspend, my computer reboots instead... When I lock and unlock the screen, Okular behaves as expected. As you use the word "slide" and mention the popping-up menu: Do you mean "Presentation Mode" instead of "Full-Screen Mode"?
Changing status, please answer David's question
David, Albert Yes, I mean what Okular calls 'presentation mode' (and which, it seems to me, displays the currently viewed page of the document over the full screen). (By the way: the keyboard shortcuts window does not maximise, which made answering the question harder than it should have been.)
There's something wrong in your DE if it does not let you maximize the configure shortcuts window https://i.imgur.com/AmJ8Fmn.png
Thanks. Indeed I do not see those buttons. Changing system themes did not help. Still, I use the 'kvantum' theme manager (to deal with qt applications); perhaps that has something to do with the problem.
