as the title state i'm noticing huge memory leaks with oxygen-gtk
theme under KDE.
With xrestop i can see with a sample application like pidgin that for
example each time i move the mouse over a popup menu resource are
never freed (pixmaps and Misc counters grows indefinitely and also
their memory occupation).
Do the leaked resources persist when the application terminates?
This is most likely an oxygen-gtk / GTK+ issue.
yes sorry but i forgot to mention that very few resources are freed when
pidgin (or another gtk app) terminate.
Example:
ps aux before running pidgin:
[...]
That may be due to heap fragmentation (memory allocated from the heap
can only be returned to the system from the end of the allocated range,
not in the middle of it).
If the pixmaps no longer show up in xrestop, their memory is freed as
far as the X server is concerned, and they were most certainly allocated
by oxygen-gtk / GTK+.
I don't think this is due to heap fragmentation I could easily made Xorg
leak hundreds of MB and they where never freed.
How is that an argument against heap fragmentation?
Pixmaps always show up in xrestop when the application is running but if
I close the application how could I know if they where actually released?
As I said, if they weren't freed, they'd still show up in xrestop.
Sorry I wrongly read the memory reported by xrestop it isn't a great
amount that could justify the leak.
Here some output:
