odp matching the description and being rendered differently in edit and presentation mode

Rendering is different in edit ("normal") mode and presentation mode for bitmaps that are scaled in one direction and then rotated.

Rendering in edit mode is OK.
Rendering in presentation mode is WRONG: Rotation is OK, but scaling is not.

Steps to reproduce:
1) create a new, empty presentation
2) import a bitmap (a rectangle does the trick best)
3) scale it horizontally to 50%
4) rotate it 45°
5) press F5 for presentation mode

Observation:
- Edit mode: The bitmap looks as expected.
- Presentation mode: The bitmap is rotated, but scaled in both directions

Expected behavior:
Rendering is correct (and equal) in both display modes.

[This is an automated message.]
This bug was filed before the changes to Bugzilla on 2011-10-16. Thus it
started right out as NEW without ever being explicitly confirmed. The bug is
changed to state NEEDINFO for this reason. To move this bug from NEEDINFO back
to NEW please check if the bug still persists with the 3.5.0 beta1 or beta2 prereleases.
Details on how to test the 3.5.0 beta1 can be found at:
http://wiki.documentfoundation.org/QA/BugHunting_Session_3.5.0.-1

Kubuntu 11.04, AMD64, Radeon proprietary graphics driver
Comment 6 A (Andy) 2013-03-24 19:33:29 UTC
reproducible with LO 4.0.1.2 (Win7 Home, 64bit)

Reproduced with the following steps:
1. Open IMPRESS
2. Copy the original rectangle with the cirle from the attachment into the new presentation
3. Right mouse click on the picture -> POSITION AND SIZE -> tab POSITION SIZE -> deactivate KEEP RATIO and reduced WIDTH to half of the original size
4. tab ROTATION -> ANGLE = 45
5. Start presentation mode

@Thorsten: Could this maybe be something for you?
