I'm not sure my comment will be relevant, but I've just noticed some tearing *at the top of the screen only* (that's barely noticeable -- in openGL 2D games like SMC for instance), when using nvidia proprietary drivers + compiz.
Please note I'm doing the following which usually gives a flawless output but not now as of Ubuntu 10.10 :
- Option "DynamicTwinView" "false" in /etc/Xorg.conf so that the right refresh rate is given by the driver (I hope nvidia will fix it one day, so that it's not necessary anymore)
- nvidia-settings : I tick sync to VBL everywhere
- CCSM : I tick : autodetect vsync + sync to VBL
This bug was definitely not there *before* Lucid. Was probably there in Lucid though. It's very noticeable in SMC or Steelstorm for instance but not much in regular 3D apps with no "2D scrolling".
