This bug I've reproduced on different rasters. For example http://gis-lab.info/share/DR/l5_19880625.img

Just tested the raster you linked and it works fine under linux and qgis trunk. I'll check also under xp and report back.

Ok, is confirmed that the issue happens under windows but not linux. Any Mac to test it?

Thanks for testing it. Sorry I don't have possibility to test bug under Mac OS.

Hi,
I think that the title of this ticket does not really match the described issue. What about changing it? maybe something like "(windows) setting transparent colours applies to wrong pixels"?
cheers

I'm not sure that issue is connected with transparency. Seems that it is Identify Feature tool issue.

If you try to click in different place of pixel you will get different values of bands.

Replying to dr:

Hi,
I cannot replicate it here with trunk under linux. Can you post please a sample of the data you are using?
