201211 - while having open a PDF file in a new window is very CPU time consuming

Status: RESOLVED DUPLICATE of bug 198954

(SeaMonkey :: General, defect)

Description

[Josep Lladonosa]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; ca; rv:1.3) Gecko/20030327 Debian/1.3-4
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; ca; rv:1.3) Gecko/20030327 Debian/1.3-4

I access from a webpage to a link which opens a new windows to view a PDF.
The CPU time used is very high all the time. The high consuming process is
Xfree86, so
I guess that it is associated to a possible loop waiting for events between
mozilla and xwindows.

Reproducible: Always

Is this a problem with non-Debian Mozilla builds?

[Joachim Noreiko]

This happens on Windows, Moz 1.6

See, for example http://tube.tfl.gov.uk/content/tubemap/default.asp

This in fact happens for all file types that Mozilla can't handle: I get both a
new blank window and the "what to do with this file?" or "where to save?" dialog
boxes.

To fix this, a link such as the following should be recognized as a download
file and the effect of target="_blank" overriden.

<a href="foo.pdf" target="_blank"></a>

Thia happens with

Mozilla 1.6
Mozilla/5.0 (X11; U; Linux i686; ca; rv:1.6) Gecko/20040401 Debian/1.6-4

CPU time consumption:

a) showing a PDF file in a mozilla window, clicked in a webpage, already loaded

69.6% XFree86
17.7% mozilla-bin

b) after closing the window (before, it would be similar, too)
 3.8% XFree86
 0.0% mozilla-bin

Difference is noticeable, as my cpu 'stressess' in a)

debian builds use gtk2
