Description of problem:
Sometimes rendering issues occur when displaying tooltips for panels. It is easier to reproduce it with multiple panels.
Version-Release number of selected component (if applicable):
Fedora release 11 (Leonidas)
Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller
Steps to reproduce (not 100% success, but it happens quite often):
1. Create 2 panels,
2. move mouse to 1st panel and let display tooltip,
3 move mouse to 2nd panel and let display tooltip,
4. 'messy' area on place of 1st tooltip is displayed together with correct tooltip of 2nd panel (look at screenshot)
Had this reported once before, and the concensus at the time was a driver bug.
Fwiw, are you using desktop effects? Tried toggling it on/off, does it make any difference?
I wasn't using desktop effects at the time of report. I turned it on yesterday, looks like issue doesn't occur with desktop effects enabled.
My bugzilla search-fu has failed me, I can't for the life of me find the previous similar report.
fwiw, I (still) can't reproduce thos on my own boxes (intel945 and radeon 9200), with or without effects.
I can't imagine it can be related to issue nevertheless I forgot to notice I am using dual-head (laptop+external display).

Aaron Seigo says it is xorg bug:
This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '11'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 11's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 11 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
