Hello listmates, I have a weird problem with the KDE4 login manager. I am using openSUSE 11.1, with KDE 4.2, but the problem also existed on KDE 4.1. I am running the NVIDIA proprietary driver with a Twinview setup (dual monitors) The problem is that the secondary screen shows left-overs or artefacts from the last running session. They also show up briefly on the primary screen after logging in but before the session is fully loaded. I sometimes also see a brief flash of them before the screen saver shows the "unlock" dialog. What are shown are basically snippets of what was shown on screen during the previous session: bits of a web page, a small part of an image file, an icon, parts of a menu, parts of a screen of game that was running under wine. Some of these left-overs repeat, some don't. It's hard to describe, and I don't know how to provide a screenshot of it. This behavior was not present in openSUSE 11.0, with KDE 4.1, and also not in openSUSE 11.1 with KDE 4.1. So I am assuming that it has something to do with KDE 4.2. At one point I thought it was due to files in the thumbnail cache (~/.thumbnails). So I cleared the thumbnail cache, but this did not change the problem. Killing the X server at the login screen also doesn't solve the problem. When X restarts, the problem returns. It almost seems as bits of a memory buffer are somehow shown from somewhere, but I have no idea form where. I could not find a bugzilla, but I am not sure I should file one, since I am using the proprietary driver from NVIDIA. (I can test with the open source driver before I do that, obviously) So first I'd like to know if someone has similar experiences, what might be the cause and what might be done. It's not a huge problem for me, since I am pretty much the only one who uses that system. But it might be a problem on a shared computer, since it might show things that the user doesn't want shown... Any ideas, anyone?
