Version: (using KDE 4.3.0) OS: Linux Installed from: Ubuntu Packages The big problem here is video tearing... its not the old tearing ati problem which just happened with compositing... its some kwin tearing problem... it just happens with kwin compositing on... I tested it with compiz and without any compositing... and there is no tearing. With tearing i mean something which breaks the screen in 2 slices overlapped... it happens in fast motion scenes...) I tested it with VLC and SMplayer, driver Opengl2(Yuv) which worked very well for other tearing problems on ati cards... xv and X11 ones... and the problem remains. This looks like some vsync problems (just like other ati easy tearing issues...) with kwin's opengl vsync option on, nothing happens... When I switch to compiz, all is fine, no compositing also works well. Kde 4.3 ubuntu packages from ppa. Catalyst Ati driver 9.7. 32 bit Ubuntu Jackalope what else? Its like the bug 193187 https://bugs.kde.org/show_bug.cgi?id=193187 but with an ati card. Thanks.
Oh right... its an Ati HD3200 card.
There are some vsync improvements in 4.6. Could you please try if that fixes it. Also nowadays there is the option to switch to the free radeon driver.
