Bug#335337: kpdf: Excessive pixmap memory usage
Package: kpdf
Version: 4:3.4.2-2
Severity: normal
When viewing large pdf files kpdf seems to use an unreasonably large
amount of X pixmap resources. After loading iand paging through a large file
(eg the IA32 SDM http://www.intel.com/design/pentium4/manuals/index_new.htm )
"xrestop" reports that kpdf is using almost 700MB of pixmaps (machine has
2GB physical RAM).
I have the performance/memory usage option to "Normal", so this seems
excessive.
Changing this setting to "Aggressive" makes no noticable differece.
Changing to "Low" fixes the excessive pixmap use, but with a fairly
severe performance hit.
Also tried on a machine with less physical ram, and the limit seems to be
one third of physical ram. I don't know if this limit is imposed by kpdf
or Xorg.
