Red Hat Bugzilla – Bug 118293
Erratic resizing of mozilla browser window
Last modified: 2007-11-30 17:10:38 EST
Description of problem: When a Mozilla browser window is open and is resized using the lower right resize grip, the resizing animation is smooth when gripping onto the extreme outer edge of the resize region. The resizing is highly erratic when the inner most extreme edge of the grippy region is selected and sometimes the dragging sticks on even if the mouse button is released. Version-Release number of selected component (if applicable): mozilla-1.6-1 gnome-session-2.5.91-1 kernel-2.6.3-2.1.253 How reproducible: Every time. Steps to Reproduce: 1. Open Mozilla browser (any URL) 2. left-click and drag on the bottom right corner of the window at the extreme inside location when the resize cursor appears 3. try to resize the window to the desired size Actual results: Window size jumps all over the place and will not stop jumping around even after mouse button is released until the mouse focus is elsewhere. Expected results: The same smooth resizing that you get if you click the extreme outside edge of the window. Additional info: ATI 8500 AIW video card
Running on an updated system using yum update to repository as of 2004-04-25. The resize is behaving much better now but it still not ideal. Instead of the sizing jumping around it will just stop and not track the cursor.
I also get this -- the mozilla window "sticking" to the mouse if I resize with the lower-right corner. It makes the system nearly unusable because it takes a lot of random moving & clicking to get it unstuck - very embarrassing :-0 when trying to show off Fedora and Gnome. This is with FC2 test 3, with all updates as of 5/8/04 - so mozilla-1.6-5 metacity-2.8.0-1
This is still there in FC2 final.
This problem still exists in FC3 test 1 yum updated right up to 2004-09-07.
With what theme? I don't have a little grippy in the lower right hand corner. I believe that's disabled for just this reason. :)
I am using the standard "Modern" theme. There are diagonal lines on the lower right corner which I call "the grippy region" that is separate from the border of the Mozilla window. Just checking now ... I notice that the "Classic" theme gets rid of that grippy region. So I guess this is just a problem when using the Modern theme or others that define that region. There is a work-around then but I would say that there is still an underlying problem when a theme defines it's own resizing region. Perhaps a general disabling of that functionality in themes is best if all window managers have their own resizing functionality ... it would at least avoid the windows spazzing out when they are fighting one another.
It's a long-standing bug. I mean it's been there for years. I think I tried to diagnose it once. I suspect it's the motionnotify compression handler wreaking havoc with the offsets in the code that tracks the location of the mouse for that kind of drag.
I noticed in W2K that Firefox has that same grippy region in its standard "Firefox" theme and it works fine. I will install and load up Firefox in my FC3-test box when I get home to see if it is handled properly there. If so, maybe there is a solution that already exists there.
Yeah, I think it's a bug down in widget/ which means it's specific to Linux.
As promised, I installed Firefox/Linux and the grippy is conspicuously absent. So either Firefox/Linux packages a different default theme than Firefox/Windows (I suspect not) or somehow the Linux version clobbers the grippy that is in the theme knowing that it will cause grief. Is there a chance of getting this grippy-clobbering code into the Mozilla Suite too? Should this just go into the Mozilla bugzilla instead/as well?
Please note that FC1 and FC2 are no longer supported even by Fedora Legacy, and that FC3 and FC4 are supported by Fedora Legacy only for security issues. Please install a still supported version and retest. If this still occurs on FC3 or FC4 and is a security issue, please reopen the bug and assign it to that version and Fedora Legacy. If it still occurs on FC5, please reopen and assign to the correct version. mozilla was removed from FC6, although the seamonkey application suite, available from Fedora Extras, is derived from it. Similar bugs may also be present in firefox, so if the bug occurs with firefox in FC6, the bug should be reassigned to FC6 and the firefox component.
