Not least of all what constitutes 'idle'. Just because you-the-user are not doing anything does not mean the system is idle. And I don't mean the background tasks. (Although I've run things like 'powertop' to see where the interrupts come from, and yes the video driver is up there in the top 5.)
I'm somewhat experienced in computers, using Linux since 1994, so I do have at least some idea of what is 'right' and what is 'wrong' ;^>
If you choose decorative eye-candy that consumes CPU then it will consume CPU.
True. But the only thing that is active is the glow around active windows, cube animation when switching desktop and active corners to 'zoom out' (forgot the official name of those features). Oh yeah, and a background image that is refreshed every 5 minutes.
But do check the archives. In one sense 30% is getting off light. I met an anomalous condition where Firefox (which is gnome-native) under KDE4 with a certain revision xserver produced XSYNC problems. Everything would run fine until a certain icon in firefox was displayed. The Sync (XSYNC) with the video card was handled badly. A different icon set, running Gnome or a small change in xorg.conf fixed it. Eventually the xserver was revised. Just a very specific code path that involved many items.
Yes, and I assume something similar is going on here, as wrote in my post... (and I assume you *do* agree that the above was a bug)
Is this a shortcoming of compiz, kwin and others?
Yes :-)
Of course it is, in just the same way that its a shortcoming of beer, sugar-donuts, red meat and chocolate.
Ehm, I'd have a problem with beer that would just have twice the number of calories without delivering me more bang for the bucks...
I reported this problem, was told about the XSYNC problem, and worked with the team to resolve it rather than condemned the software and developers. But then I've been a PM as well as having worked in ATE.
I'm not condemning anyone. I just point out a flaw. What's wrong with that?
