Version: (using KDE Devel) Installed from: Compiled sources Compiler: gcc version 4.1.1 (Gentoo 4.1.1-r3) OS: Linux The newsticker applet is extremely slowing down my system. When I am not running it my load average is at about 1-2 % but with this one open it goes up to more than 20 % (running on an intel dual core with 3 Ghz). And because I think the engine is the reason for the slowness (the scrolling text in detail) i'm submitting it here.
this is because QGraphicsView's clipping mechanisms in 4.3 are horrible. this is a known issue upstream. we also have the ability, finally, to simple scroll() item content with 4.4, something we don't have in 4.3. in any case, this is a known issue but not something plasma itself can fix. it should magically go away in kde 4.1, however.
this is an upstream issue, nothing that we can do about it. i'm not going to keep upstream issues that have been reported alive here. i wish there was an 'upstreamed' resolution option (bugzilla is so tuned for non-open source software development it's hardly funny)
