Comment 24 for bug 98783

X server resident memory usage went back up to 500MB and stayed that way even after I killed all GUI programs except the terminal and panel applets. Logged out and back in to restart X server. Usage went down to 200MB virtual and 69MB resident. Reloading firefox, and all my tabs, did not affect X server memory usage. Reading a document:
ftp://ftp.ams.org/pub/tex/doc/amsfonts/amsfndoc.pdf
(font heavy, since it describes a font) using okular caused X server resident memory to jump up to 200MB and virtual memory to increase by about the same amount. However, this memory was freed when I exited okular. Using evince to read the same document did not cause any increase in X server usage. xrestop is still reporting 17MB of usage.
