116926 - Tab's border not fully redrawn after tab switch

Status: RESOLVED EXPIRED

(SeaMonkey :: Tabbed Browser, defect)

Description

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.7+)

If there are several tabs open and one is closed sometimes the border of the
last selected tab is not drawn correctly.

It looks like a z-ordering problem.

Reproducible: Sometimes
Steps to Reproduce:
1. Create 6 or 7 tabs
2. Select one of the tabs in the middle (Lets say the 3rd one)
3. Select another one of the tabs in the middle (Lets say the 4th one)
4. Close that tab (4th one)
5. Select another tab (This seems to work the best if the 5th or 6th tab is
selected)

Actual Results:  The left side of the previous tab doesn't redraw with the
correct color.

Expected Results:  The borders should redraw correctly.

The 2nd Tab is selected, but the 4th Tab's left border is still white.

Attachment: Another case where mozilla does not redraw the tabs

This was from Windows 98 SE, and the first and last tabs did not redraw
properly.

This bug appears to have been fixed with the recent checkin for bug 137836. Can
anyone else check this, and close this bug?

Comment 8

[Joonas]

Nope, this ain't fixed. I followed the steps to reproduce this and I still see
weirdness. Some tabs have thinner borders than others. Win2000, build 2002042403.

Comment 9

[Brian G.]

This still happens, see my previous message.

Which build are you using? The fix for bug 127836 was checked-in on 04-24, so
you should test it with a recent build.

[Andreas Kunz]

The bug is still there in Build 2002042510 (Win2k).

Michiel, you should read comment #1 carefully: this bug is *not* about a tab's
missing right border, when the tab to its right is closed (that was bug 132687
and others and is fixed now), but about tab borders that are missing their shadows.
This bug here appears for me even if there are no tabs closed!
Just open a lot of tabs and watch for the borders between inactive ones: some
are darker, some lighter.

BTW, comment #6 shows that kind of bug that is fixed now, but not that kind that
reporter Jeremy had in mind (as I suppose from his screenshot and description).

I think I see the problem now. After trying the testcase I saw that one tab had
a right border, but not corrctly. Normally, there should be a gray line, and
then one black. Next to that, there is a white line from the following tab.
But sometimes I see that the black line is missing. I will attach a screenshot.
However, the screenshots clearly shows a completly missing line.

Attachment: Screenshot with black line missing.

The screenshot. Lower part is magnification of parts of upper part.

This bug report is registered in the SeaMonkey product, but has been without a comment since the inception of the SeaMonkey project. This means that it was logged against the old Mozilla suite and we cannot determine that it's still valid for the current SeaMonkey suite. Because of this, we are setting it to an UNCONFIRMED state.

If you can confirm that this report still applies to current SeaMonkey 2.x nightly builds, please set it back to the NEW state along with a comment on how you reproduced it on what Build ID, or if it's an enhancement request, why it's still worth implementing and in what way.
If you can confirm that the report doesn't apply to current SeaMonkey 2.x nightly builds, please set it to the appropriate RESOLVED state (WORKSFORME, INVALID, WONTFIX, or similar).
If no action happens within the next few months, we move this bug report to an EXPIRED state.
