Comment 26 for bug 519583

This _might_ be a similar/related bug: starting this morning, my Gnome Panel clock is stuck at a specific time. If i remove the clock (or kill its process), the image of the clock stays on the panel but it no longer reacts like a clock (e.g. right-clicking brings up the panel menu, not the clock menu). Re-adding it doesn't solve the problem - it's still stuck at 11:28.

The system clock is not affect: "date" shows the proper time. See attached screenshot.

Using Ubuntu 10.4 clean install (except for my home dir, which was been around at least 4 years) on x86.

i suspect that comvpiz has something to do with it, but that's mere speculation based on similar problems i've had in the past when using compvis.

[3 minutes later...] As a matter of fact... disabling desktop effects (setting them to None via System->Prefs->Appearance) fixed the problem.
