Description Thomas D. 2013-03-05 18:40:29 UTC
While hardware acceleration is enabled, pictures I scanned (300dpi and 600dpi) are displayed distorted in presentation view while looking fine in edit mode.
Images taken from the internet look good in both views.
(See samples in attachment)

This problem occurs on 
- Windows XP SP3 
- Xubuntu 12.04; 
both with Libre Office

The attachment contains:
- FromInternet.jpg - image from the internet that displays well (edit and presentation)
- PresentationView.png - Screenshot of presentation view with hardware acceleration enabled containing the provided images
- Scanned300dpi.jpg - sample image scanned with 300dpi
- Scanned600dpi.jpg - sample image scanned with 600dpi

When I disable hardware acceleration the images are all displayed fine.

Maybe I'm a bit to fast here. I talked to you via IRC :-).
Is it possible for you to attach mentioned attachments?

PS: I recall you said this is already reproducible using Therefore I mark this as a bug of LibreOffice This is the oldest reproducible version we can reproduce this behavior (probably reproducible using older versions too).

Kind regards,

sample images and screenshot of the presentation

Seems as if I did a mistake when trying to add the attachement. 
The zip file I wanted to upload was too big. So I had to resize the images a bit.

So here it is ;) Thanks for your hint.
And yes, you're right with the first version it occured.

not reproducible with LO (Win7 Home, 64bit), looks fine in presentation view and edit mode with and without hardware acceleration

Does this issue still persist for you with the latest release of LO?

Can anybody else confirm this behavior?
Comment 4 Jacques Guilleron 2013-03-24 15:43:03 UTC
No issues for me with LO and LO, Windows 7 Home premium, with hardware acceleration or not. Prehaps a Linux issue?

Comment 7 Thomas D. 2013-03-24 16:10:44 UTC
I updated to the recent version (LO and tried again. As you can see in the attachement the problem seems to be still there. I'll see whether I can test it on another machine with Windows where this problem occured too.
Comment 8 Thomas D. 2013-03-24 16:22:06 UTC
I just tested it on a Windows XP SP3 machine. Same problem here.
Images ok with HA deactivated and distorted with HA activated.

Could you write more detailed information about your video hardware and software then?
Comment 10 Thomas D. 2013-06-26 19:26:24 UTC
I have a NVidia GeForce GTS 450 with the drivers provided by Xubuntu. 

As far as I know the Laptop that the problem occured with too has some kind of Intel HD Graphics Chip under Windows XP, but I have to check that for I don't have it with me right now.

What kind of additional information do you need?
