Can you reproduce the issue with desktop effects disabled? (hit ctrl+shift+F12)
It is irregular, I can not reproduce it, sometimes 2 weeks pass and everything goes well, and other times, in 2 days, this problem happens with the clock icon
Could be a graphical glitch in the driver. That's why if it appears the next time. Try disabling effects and see if it fixes the issue.
Which graphics driver do you use?
It happens, very occasionally, when it happens again, I'll prove what you're saying, but I think maybe it happens more at certain panel heights, I'm not sure.
This is my graphic driver:

Always works fine for me.
