Description of problem: When tab headers are shown in maximized window then the 2nd and 3rd lines from the bottom are hidden. Version-Release number of selected component (if applicable): gnome-terminal-2.24.0-2.fc10.i386 Steps to Reproduce: 1. start gnome-terminal and maximize 2. run for example "seq 100" and write your name without hitting enter and memorize the topmost and last lines 3. start new tab with shift-ctrl-tab 4. back to tab 1 with alt-1 Actual results: 5. notice how the top and bottom lines have been preserved even though the available area has shrinked - but in the example the lines 99 and 100 have disappeared Expected results: The window should threat the introduction of tabs as a resize and scroll the topmost lines out of view.
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle. Changing version to '10'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Same problem with gnome-terminal-2.25.91-1.fc11.i586 in rawhide
I discovered that this actually happens with ANY event that reduces the number of lines, which makes this a bit nastier. It doesn't have to be maximized: 1. Start a gnome-terminal with two tabs. 2. Run "seq 100" in both tabs. 3. Resize the window so that it's a few lines shorter. The active tab will scroll lines off the top, so nothing is lost. The other tab will permanently lose a few lines from the bottom, as in the initial report. Also note that the loss doesn't occur until you actually switch to the background tab. If you resize the window shorter, return it to the original size, and then look at the background tab, then nothing will be lost.
Humm. Can't reproduce.
I still can with gnome-terminal-2.25.91-2.fc11.i586: shift-ctrl-n alt-f10 seq 100 shift-ctrl-t alt-1 - and notice that 98 now is the last number
Created attachment 339613 [details] [vte] ensure that scroll_delta is always adjusted When gnome-terminal's height is reduced, the active tab's terminal gets a vte_terminal_size_allocate() call, which queues an adjustment to the scroll_delta based on visible_rows to ensure that the scrollback moves correctly. However, when you then switch to a different tab, that terminal gets a vte_terminal_set_size() first, which will update terminal->row_count with the new height. Only after it's visible does it get vte_terminal_size_allocate(), and there the computation of visible_rows thinks that there's no reduction (since terminal->row_count already matches the new height), so it doesn't compute the new scroll_delta. This patch moves the scroll_delta computation into set_size so it is always kept current.
I am running with the patch and can confirm that it works.

I've now copied this bug upstream: http://bugzilla.gnome.org/show_bug.cgi?id=588033
This problem still exists on rawhide, and the patch still works to fix it.
Behdad, do you still can't reproduce the problem? I just saw Gnome 2.28 Release Planning and noticed the Hard Code Freeze is entering September 14.
Fixed upstream. Will be in f12.
