Package: gnome-shell
Version: 3.4.1-5
Severity: normal
Dear Maintainer,
This problem occurs on a Nouveau system with two monitors.
EXACT STEPS LEADING TO PROBLEM:
1. create new user and log in with this user (to prevent config probs)
2. open preferences monitors
3. uncheck screen mirror so you have a desktop with two screens
4. use this new setup
5. open some windows.
6. open chromium and open a second chromium window. Put the second window
on another workspace. Open some tabs on both chrome windows.
Put one window on the left, the other window on the right screen (other
workspace, of course)
7. open an epiphany window
8. do your daily work...
EXPECTED OUTCOME:
All elements of all applications are rendered fine
ACTUAL OUTCOME:
chrome: Tabs titles get unreadable artifacts. On "mouse over" the artifacts
may move to other tabs. When leaving the tab with the mouse the artifacts
change again
terminal: The whole text field gets artifacts sometimes.
epiphany: artifacts on different parts of the web pages
REPRODUCIBILITY:
6/10
OTHER COMMENTS:
This is quite complicated to reproduce. There is no way to make a
screenshot of the artifacts :-(
The problem occured at some time in the last weeks
when moving from gnome3.2 to gnome3.4
(with gnome-shell 3.2 too) so that may be a problem with some library used
by gnome-shell and not gnome-shell itself. Moving the focus between windows
or window elements may change the artifacts. This problem occurs with stock
kernel 3.2.0-2-amd64 too.
