It's defiantly looking like a leak or 'caching', I've run xrestop and taken
snapshots at various time. From a 'clean' start-up of KDE and then doing
some stuff or waiting a while.
I don't have performance issues, until after quite a while, but I'll look at
the xrender backend and see if that help at-all etc...
I'll take a look at the bug reports, one of the things I was intested in was
getting more into identification and fixing of bugs etc... which is why I
posted to devel-list first. but will follow up looking at the bug reports,
hopefully being able to improve on them and possibly fixing them if that's
not been done yet.
Opening windows causes pixmap usage to go up
and minimising windows does cause it do go down, and then closing down
again.
But it does't return back to the previous level and creeps up after more
'work'
there is a drop betweeen @2011-01-09 09:08 and 1:17am. So I'll leave things
overnight and get it back to running the same tasks etc... to see how things
pan out.
so at the moment 1:17am
