Description Frankie Robertson 2006-05-31 14:05:51 UTC
Please describe the problem:
When an some applications decrease the screen resolution, the increase it again a panel positioned at the bottom of the screen will be moved up.

Screenshots:
Before: http://img258.imageshack.us/img258/344/screenshotbefore5by.png
After: http://img290.imageshack.us/img290/5996/screenshotafter9bi.png

Steps to reproduce:
1. Run X-COM: UFO Defense under wine with the command "wine ufo.exe".
2. Exit the program

Actual results:
The program will switch the resolution to a smaller one then when finished then larger one.
If the gnome-panel is positioned at the bottom of the screen it will be moved up and will have to be dragged down again.

Expected results:
The panel should will adjust and reposition to the bottom of the screen.

Does this happen every time?
Yes.

Other information:
Most native linux applications that switch resolution are pretty well behaved about it and this doesn't happen. X-COM under wine is the only program I've seen this problem with so far, but it could easily be more widespread than that.

Similar to bug 338537 and bug 344631.
Comment 2 Reinout van Schouwen 2006-07-01 19:01:27 UTC
Not only that, the positions of the applets and launchers on the panel will be changed as well, regardless of whether 'Lock to panel' has been enabled or not for panel items.
Comment 3 Reinout van Schouwen 2006-08-06 11:14:21 UTC
Still valid in 2.15.x

Since this bug is still present in gnome-panel 2.18.x could someone update the version number in the bug report?
Comment 7 petrosyan 2007-05-25 16:59:37 UTC
Here is another way to reproduce this bug:

I am going to assume that the default screen resolution is 1280x1024. The bug
doesn't depend on it but it makes it easier to explain it.
1. Log in. Go to "System/Preferences/Screen Resolution" and change the
resolution to 1024x768. Keep the new resolution.
2. Log out.
3. Log in again under the same user account, go to "System/Preferences/Screen
Resolution" and change the resolution from 1024x768 back to 1280x1024.

Actual results:
Workspace switcher and trash applet forget their correct location.

Expected results:
Workspace switcher and trash applet should be in the lowest right corner of the
screen.

Additional info:
Clock applet, volume applet, and notification area remember their locations
correctly.

Updating version field & confirming.
Comment 11 Vincent Untz 2007-06-29 14:03:09 UTC
Fixed in trunk (the applet repositioning is another bug which is not fixed, but already known).
