I see the same symptoms using the "radeon" driver with my Radeon X1550. This is with Jaunty upgraded to KDE 4.2.4.
Don't understand why this was marked as a duplicate of bug 343944. The symptoms are not the same. I see no memory leak as described in that bug. ** This bug is no longer a duplicate of bug 343944 Epic plasma memory leak (0.1 mb / sec) -- [X300] Randomly, the texts and backgrounds on plasma widgets start to disappear https://bugs.launchpad.net/bugs/351283 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
