KPDF draws lines out of the window.

[Mauro De Lucca]

Binary package hint: kpdf

When i open and navigate through a pdf file, KPDF draws some diagonal lines on my screen.

[Some Thing (something)]

I can affirm this bug, for my machines (about 4) this always happens (from breezy to gutsy).

Ihave attached my screenshot.
If anybody want's to reproduce this, just open a big (or if you have slower machine enough if you open a little) pdf, and scroll that fast. The pages that isn't being rendered yet have a big X instead of the page's contents, that X's lines gets out and makes that lines...

Which video driver do you use?

If you use a VIA video driver, then http://bugs.kde.org/show_bug.cgi?id=138076 is for you.

[Mauro De Lucca (pcniatic)]

Yes, i was using a VIA video driver, although i cant confirm if it solves the problem because i am not using that computer anymore.

[Some Thing (something)]

I think it isn't depends on the video card.

I has this problem on different cards too:
- Nvidia (6600)
- Intel Integrated G950
- Via S3 Unichrome
- Trident something...

This problem is very annoying. I think this lines comes from the pages that isn't rendered yet, and which only has this grey X. If you scrolls fast, faster than your machine renders (at my shitty machine it isn't rare) then these Xes somehow gets out from kpdf.

Once i saw that this lines appeared on an image inside a webpage in firefox. It isn't cleared when i scrolled up/down, neither for simply refresh (without redownloading the image). So i think it somehow overwrites the other applications memory, or buffer, or something like that. (It's just an opinion i'm not adept in this stuff).

I have attached a video, that describes the problem more precise, than my english grammar;)

added upstream bug

[Harald Sitter (apachelogger)]

Does this still happen in KDE 4.1's Okular (KPDF replacement)?

[Some Thing (something)]

No, it doesn't.

[Lydia Pintscher (lydia-pintscher)]

Marking as fix released then.
KPDF will not be available in the next Kubuntu release. Only Okular.
