Version: (using Devel) Installed from: Compiled sources The system tray shows no symbols. The space seems to be reserved. But clicks are not handled. See following screenshot attachment.

No change, if I remove/add the tray or resize the panel or restart plasma. kde-version: 4.1.85
What graphic driver are you using? because everything that has to do with those icons is most of the time a driver problem
I use the "radeon" driver, and have a radeon-9250 card. This still worked some time ago (around kde-4.1.80). The problem also appears with kwin-effects off.
It happens also here (well, I can see black boxes instead sometimes) with an Intel driver. I can also say that it happens to me only if I have the system tray embedded into the panel, if I place it on the desktop I can correctly see the system tray icons.
BTW, KDE trunk (from yesterday 19 december) here.
either driver or Qt issue. Suse had a build of Qt for a while that exhibited this problem.
Actually yes, it is a driver issue. On the intel driver for example, removing Option "MigrationHeuristic" "greedy" from xorg.conf made it, and now it is working normally and can see icons without problems.
ok, that pretty much confirms this problem indeed... since it's the Nth time we've seen it and every time it's a driver or Qt.
if this is a driver problem: why did the tray work for me with kde-4.1.80 and the same driver (same driver-version)?
any number of reasons, Volker. the code has changed between .80, .85 and now; perhaps your installed Qt is to blame (see comment #7); perhaps it's a setting in your x.org that only now started causing problems. in any case, every, single, time this precise issue has been reported we've tracked it down to either Qt, the x.org driver or an x.org config setting. i really wish reporters couldn't re-open their own reports. 95%+ of the time it's a wasted action.

I resolved the problem: this problem does not appear anymore with qt version 4.4.3 (newest from opensuse build service). I previously had installed qt-4.4.0
