I have the same issue with Plasma Active 3 on Nexus 7.

Fixed, see thread "Rendering problems in kwin and active" on the active@kde.org list.

Please reopen if the problem resurfaces.

Jfyi, I filed a submit request for a patch to solve this issue for the current trunk testing of Plasma Active on MeeGo cobs: https://build.pub.meego.com/request/show/7761

If this can be tracked back (again) to the Qt patches Nemo carries to adjust what the default QDeclarativeView (iirc it was that class) does, that patch should simply be removed as it creates a non-standard Qt.
