I have some further diagnosis and a workaround: when the bug is manifested, the file .kde4/share/config/okularrc contains these lines:
[Desktop Entry] FullScreen=true ... [MainWindow] Height 1050=1050 Height 1200=1201 MenuBar=Disabled State=AAAA/wAAAAD9AAAAAAAABXgAAAQaAAAABAAAAAQAAAAIAAAACPwAAAABAAAAAgAAAAEAAAAWAG0AYQBpAG4AVABvAG8AbABCAGEAcgAAAAAAAAAFeAAAAAAAAAAA Width 1400=1400 Width 1600=1601 (My normal screen is 1400x1050. I sometimes use a 1600x1200 screen, although I haven't used that screen since I started using okular, so I'm not sure where those lines came from, except maybe a kpdf installation.) Changing this to [Desktop Entry] FullScreen=false ... [MainWindow] Height 1050=965 Height 1200=1000 State=AAAA/wAAAAD9AAAAAAAABRQAAAOoAAAABAAAAAQAAAAIAAAACPwAAAABAAAAAgAAAAEAAAAWAG0AYQBpAG4AVABvAG8AbABCAGEAcgAAAAAAAAAFeAAAAAAAAAAA Width 1400=1300 Width 1600=1500 makes the bug disappear. (I've attached the complete buggy okularrc.) --Dylan Thurston
