The SVG in question
My distro: Kubuntu 13.04 64-bit with KDE 4.10.5
Steps to reproduce
0. Start Libre Writer
1. Load the attached SVG file (might work with any SVG)
2. Change any image slider (Contrast, transparancy, brightness or color balances)
3. No change to the image
Behaviour in Impress and Calc:
Any change to the image causes it to be rasterized (poorly in both raster and vector resolution), then filters are applied.
While the behaviour in Impress and Calc would be a feature request of sorts (do a better job rasterizing or keep the vector nature), the behaviour in Writer is a bug in my oppinion, since there is no information to the User, as to what is causing Writer's refusal to change the image in the indicated way.
I cannot confirm it. The color adjustments work fine for me. I use

I work on Windows7.
I have no trouble reproducing this bug in Windows 7 (64 bit) in a portable install of version 126.96.36.199. Build ID: 7e4286b58adc75a14f6d83f53a03b6c11fa290
Are you sure you are doing just the indicated steps with the file I provided?

Output on my end
Good thinking. I can now confirm, that we see a different output. I attached a screen shot who the file you attached is rendered here (100% unchanged).
I suspect it's got to do with the font. I will make a version of this with the writing in the originally intended font rendered to a path.
It might be that it works or doesn't work depending on what font type the replacement font is.

Colored square in SVG
I can repoduce the bug here even with the very simple SVG that I have now attached (just a square in a solid color). So the font does not seem to be to blame.
Can somebody else please try to reproduce this? I can't be the only one with this problem.
Reproduced with LibO 188.8.131.52 on Win7
I'm not a specialist in image processing, but for me it looks like this :
- a SVG image is fully scalable, without "stairs" effect on obliques,
- the inserted SVG remains fully scalable (verified with a big magnification), so I suppose it remain stored in SVG,
- the SVG format specifies "hard" colors ; maybe the color effect is done but masqued by an inappropriate re-application of the "hard" initial colors ; or maybe the image must be rasterized in order for the color settings to work, and for a reason I can't explain that rasterization is not done,
- I wonder whether the rasterization capabilities depend on the hardware and the OS, this could explain the different experiences of the bug.
In the odt file Regina provided, the svg is not rasterized, yet in her screenshots the color is changed.
Since I have reproduced it on Linux and Windows on this machine, I think it might be hardware related.
With comment 9 I'm not sure what to make of this. I can't confirm but requesting additional input from developers.
Ubuntu 14.04 x64
LibreOffice 184.108.40.206 rc
