Created attachment 327822 [details] Expected results Description of problem: I have a bash alias that spawns vim in a dedicated gnome-terminal with a particular profile for text editing. Occasionally, it will come up with blank lines where text should be, which will persist until I scroll down several times in vim, use the menu item 'Terminal->Reset', or do '!reset' in vim's command mode. The corruption is sporadic, and will happen several times in a row, then go completely away for a while. Occasionally, I will get the message '(gnome-terminal:16737): Vte-WARNING **: No handler for control sequence `device-control-string' defined.' and the gnome-terminal command will not exit/go into the background, as if I had added --disable-factory to the command line. Version-Release number of selected component (if applicable): The problem has been present since Fedora 8, but I only have versions for F9 and F10. F9: gnome-terminal-2.22.2-1.fc9.x86_64 vim-enhanced-7.2.060-1.fc9.x86_64 F10: gnome-terminal-2.24.2-2.fc10.x86_64 vim-enhanced-7.2.060-1.fc10.x86_64 How reproducible: Frequently, but not perfectly. It seems to only hit files larger than the geometry specified on the command line. I have not been able to reproduce without specifying geometry. I usually use --window-with-profile=Editor, but this is not required. The 'Editor' profile uses a smaller font and hides the scrollbar and menu, but this is reproducible without those changes. I believe a file with more lines than the geometry may be a requirement, but have not investigated that very far. Steps to Reproduce: 1. gnome-terminal --geometry=80x50 -x /usr/bin/vim filename 2. Repeat until corruption occurs; this may be 10s of retries. Actual results: See attachment 'Actual results' Expected results: See attachment 'Expected results' Additional info:

This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '10'. 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 10'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 10 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: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 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.
Reopened, as this is still present with F12: gnome-terminal-2.28.1-1.fc12.x86_64 vim-enhanced-7.2.245-3.fc12.x86_64
Created attachment 431189 [details] a colored diff - reproduces the bug when viewed For months I've been seeing a problem with occasional missing lines of text when viewing git diffs. It may or may not be the same bug. Today I found a 100%-reliable reproducer. Get the attached file (colored-patch) and do: 1. gnome-terminal --geometry 120x44 -x less -r colored-patch 2. Scroll down one line using the down arrow key. 3. Scroll back up one line using the up arrow key. Actual result: The patch description disappears. Even when dragging the mouse selection through the area there is no trace of any text on those invisible lines. Pressing CTRL+L to redraw makes it appear. Expected results: The patch description should be visible all the time. 100% reproducible in gnome-terminal-2.30.1-1.fc13.x86_64 and gnome-terminal-2.31.3-1.fc14.x86_64
It is reproducible in XFCE's Terminal too, so the bug is probably in the vte library which is shared by both.
This is indeed a vte bug, and I have been seen it for a while. Let me look into it.

I've bumped the version to F13, as I still see this here and can easily confirm with Michal's test case. Behdad, if you've been able to reproduce on F14 or rawhide, please update accordingly.
I can still reproduce it on F14.

Still reproducible in F14: vte-0.26.1-1.fc14.x86_64 gnome-terminal-2.32.0-1.fc14.x86_64 Once I install F15, I'll try this there and update accordingly.
Still reproducible in F15: gnome-terminal-3.0.1-1.fc15.x86_64 vte-0.28.0-1.fc15.x86_64
Still seeing this in F16. gnome-terminal-3.2.1-2.fc16.x86_64 vte-0.28.1-1.fc16.x86_64
Also getting this with vte3: vte3-0.30.1-3.fc16.x86_64 In fact, the corruption happens when editing almost any file with highlighting, making it quite difficult to use.
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
David: Do you still see this with f15 and vte-0.28.1-1.fc15 ?
cloned for vte3 as bug 783212.
This is reproducible with vte-0.28.1-1.fc15 on F15 using the steps in comment 5. As Michal noted, I also see this in vte3 on F16.
