Description min 2005-07-30 19:47:58 UTC
Version:           3.4.2 (using KDE 3.4.2, Kubuntu Package 4:3.4.2-0ubuntu0hoary1 )
Compiler:          gcc version 3.3.5 (Debian 1:3.3.5-8ubuntu2)
OS:                Linux (i686) release 2.6.10-5-686

How to reproduce:

- go to distrowatch.com
- let the mouse pointer hover over the up/down images on the extreme right
- a text like 'yesterday: 400' will be displayed. this is the img title
- move the mouse away 
- part of the screen area where the text has been shown will remain blank. it can come back (be displayed again) if you do the whole thing again

The relevant html code is 
   img src="./images/other/aup.png" alt="<" title="Yesterday: 359"

I'll try to attach a screenshot

This is how it looks like after several hoverings.

Upon further recollection I realised that:

1. the bug doesn't occur with the 3.3 branch
2. I don't think the bug occured with 3.4.1 It might be a regression introduced with 3.4.2, but I'm not sure of that and have no fast way to downgrade :)
3. I'm using Kubuntu, which in turn uses X.org. I use 3.3.2 on SimplyMepis, which uses XFree86. So perhaps it has something to do with X.org

Also happens with SUSE 10.0, provided the konq window is narrow enough.
Comment 4 Philip Rodrigues 2006-09-05 21:08:44 UTC
Does the problem still exist for you in KDE 3.5? (It doesn't for me)
Comment 5 min 2006-09-11 13:46:35 UTC
Yes, I have the problem with KDE 3.5.3 (on FreeBSD)
Comment 6 Philip Rodrigues 2006-09-11 23:18:18 UTC
Maybe a graphics driver problem? What graphics card do you have?
Comment 7 min 2006-09-12 00:36:25 UTC
I have some on-board sis card now, but when I reported this I had radeon. Also I firt noticed it in Kubuntu, later in SUSE, now in FreeBSD. As I said in one of the previous comments, it didn't happen with KDE 3.3 (SimplyMEPIS, I think).

I really don't think it's either the graphics card or the driver (or anything else system related) - however it may be X.org related just as well as KDE related. I can't tell that.
Comment 8 Martin Fitzpatrick 2007-01-08 02:29:42 UTC
Confirmed with KDE 3.5.5 / Kubuntu 6.10. The blanking also occurs if the window is sized from Maximised to Restore size, and then scrolled to show the area in question.  Appears to be a limit to the area blanked (i.e. the distro name field is left untouched).

Notice in the source that < & > are entered bare, rather than as entities, in the alt for the page, while the page is marked as XHTML strict:

<td class="News" style="text-align: right" title="Yesterday: 163">150<img src="./images/other/adown.png" alt="<" title="Yesterday: 163"></td>

Secondly, page contains a number of statements along the lines of:

if(ScreenWidth > 0 && ScreenWidth < 901){ ...etc.

Bug disappears when page is downloaded & viewed offline (without images/etc.)
Comment 9 Martin Fitzpatrick 2008-04-05 23:01:17 UTC
Appears to be fixed in 4.0.3, cannot reproduce. Whats the situation in 3.5.9?
Comment 10 James Spahlinger 2008-04-20 06:46:01 UTC
This is not reproducible in konq 3.5.9 either. I'm closing this bug.
