Status: RESOLVED WORKSFORME

(Core :: Graphics, defect)

Description

[James Kitchener (:jkitch)]

Attachment: screenshot of duplicated line

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0 (Beta/Release)
Build ID: 20131208030204

Steps to reproduce:

Open a window in an Australis build and press the new tab button.

(Tested in both latest nightly and a self-compiled build based on latest mozilla-central)


Actual results:

The line in the middle of bookmark button (between the star/list icons) is duplicated (see duplicated attachment).  When moving the mouse over the bookmark button, the additional line disappears, however the line now appears to have a gap in it (see gap attachment).  

The bug doesn't always occur.  It may be necessary to close the created tabs and and repeat the process.




Expected results:

No graphics glitch should occur

1. Move "Developer Tools" button to navigation toolbar
2. Click "Developer Tools" button
3. Click "Toggle Tools"

The graphics glitch should (but not always) appear.  It only manifests itself when toggling the tools from hidden to visible.

Once again, I am unable to replicate this behaviour with Direct2D disabled.

James, can you still reproduce this issue?

After testing with latest nightly:

* No vertical lines appear between the  bookmarks buttons most of the time.  (Very rarely a single line appears).
* Most of the time there is a small mark between and below the two buttons (you may need to zoom in to see it). It seems to be the same mark that appears in the "line with gap" screenshot (attachment 8344464 [details])
* Devtools button corruption still occurs.

Update:  After testing with the latest nightly, the appearance of multiple lines (as shown in attachment 8344463 [details]) has returned.

Bas: is this your area? Likely to be a graphics driver bug (blacklist it?), or something on our end?

Comment 9

[Justin Dolske [:Dolske]]

Untracking from Australis as it doesn't appear to be a common issue.

I don't believe this is still occurring.

That is probably the case.

I no longer have ready access to the computer which suffered from this problem, but I don't recall triggering this bug when I used it in the last few months.
