It is a QoI (qualitiy of implementation) issue on the X server, not necessarily a bug. Nevertheless, it is affecting okular users. Other pdf/djvu viewers are not affected by this problem. This diminishes the value of okular compared against those other viewers. The problem is very serious when you are using okular on a remote X server with low memory while okular runs on a machine with lots of RAM: my case when reading docs on a 1 GB X server with okular running on a 8 MB machine. Eventually, the X server starts swapping and becomes very slow. Which lead us to the crux of the issue: okular developers explained to me that the agressive usage of X server pixmaps is geared towards fast perfomance showing pages. After months using okular with the Low memory setting, I've never experienced slowness. Actually, either with the Low memory setting or with the Normal setting it feels as fast as xpdf, for instance, which does not use the pixmap trick at all. This experience includes remote X sessions over slow wifi networks. So, unless someone can justify the superiority of the pixmap approach on terms of improved reading experience (not just raw displayed-pages-per-minute, we are talking about displaying a static image for reading) I humbly suggest to use the Low memory setting as the default or, better, do not use the pixmap trick at all. The memory used by the X server grows with the Low memory setting too, although much less than the Normal setting, where is no rare to see the X server's memory reaching gigabyte levels after some days of light usage. You can argue that it is an Xorg problem (it really is an Xorg problem that you are storing 1 GB of pixmaps on the X server?) but okular users will perceive it as a okular problem. -- Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Okular-devel mailing list Okular-devel@kde.org https://mail.kde.org/mailman/listinfo/okular-devel
