One of my main beefs with X--and I'm just assuming it's X's fault since I see it on Mac OS apps ported from Linux, as well as in the Linux desktop--are visual artifacts when redrawing parts of the screen.


This is something that's been solved a long time ago by compositing window managers. Desktop graphics on X are every bit as smooth as on win7 these days.

Hmm, that doesn't sound like a full solution to the problem. If I remember correctly, these window managers only work with 3D acceleration turned on--what happens if you use 2D-only drivers? And secondly, doesn't that only cover window moving and resizing? What about the contents of the windows?

If you don't want to use proper drivers, you don't really have the right to complain that things don't work well for you.

Classical problem with X was that stuff moving over your window caused bad artifacts (typically leaving a blank area until repaint was done). This doesn't really happen anymore. I don't know what you mean by problems with contents of the windows, everything seems to work fine for me.

KWin includes a 2d compositor (switch to Xrender mode) and you can always use xcompmgr. This mode is often faster on, e.g., radeon cards using the OSS drivers.

Only partial truth. I have generally found the situation to be wildly variable and greatly affected by various point revisions. Generally it has been mildy acceptable and never as smooth or consistent as osx and win7.

There are qt and kde apps that are quite a bit smoother on windows than on linux using the Xrender backend.

And one of the things that really gets to me is the fact that both major compositors seem to become sluggish and act weirdly after some uptime.
