Version: 0.8.1 (using KDE 4.2.1) OS: Linux Installed from: Unlisted Binary Package Okular's presentation mode window does not refresh sometimes when main okular window is unmapped. The steps to reproduce are the following: 1. open okular 2. open okular's presentation mode (in floating mode) 3. move presentation window (but not okular's main window) to another workspace 4. go to that workspace 5. see big empty gray window This is observed in tiling window manager xmonad, but does not look like xmonad's bug. Resizing presentation window makes okular to draw the contents of window.
It got even worse in Okular 0.10.4. Now to reproduce the bug you just open presentation mode (no need to move to another workspace), and even pushing PageUp/PageDown buttons does not help (it helped earlier, as I recall). Resizing the window still helps.
Unable to reproduce in okular 0.13.3, KDE 4.7.3. Roman: Can you tell me how exactly you moved the presentation window to a different workspace? I'm opening the presentation mode, hitting Alt+Tab, then dragging the presentation window to a different workspace and the presentation window appears normal.
