[Solved][BUG][Linux] Out of camera JPG displayed incorrectly

[hpmickey]

I just have filled this bug report through https://www.surveymonkey.com/s/ASPFeedback (the attachment upload ID was 313):

JPG displayed in AfterShotPro (Linux) differs from the same JPG displayed in anything else (Bibble5, GIMP, various viewers).

1. opened JPG in AfterShotPro with default settings
2. noticed a blotchy green noise in some areas
3. checked the same JPG in Bibble5 (was ok), then in the the GIMP (was ok), then in several other viewers (also ok)
4. closed ASP and the other SW, cleared ASP and B5 caches and tried again with the same result

NOTE: I have the option Preferences | Color Management | Monitor Profile | System Default checked, in both ASP and B5

This crop shows a dithering (or noise). Left: Bibble5, middle: AfterShotPro, right: GPicView

I uploaded the original (out of the Sony A500) jpeg to surveymonkey as well.

Have anybody else encountered anything similar? I would not care about displaying jpegs in ASP, but I have problems with the same (i.e. dark green) areas when converting raw files.

I also tried to set monitor profile in B5, ASP and GIMP to /opt/AfterShotPro/supportfiles/Profiles/DeafaultMonitor.icm, then to sRGB Color Space Profile.icm - with the same result.

I run ASP on Linux Fedora 12 machine. It seems to work correctly in Windows 7. Briefly tried there and both ASP and IrfanView displayed the original jpeg more or less the same way.

EDIT: added the [Solved] keyword to the subject

a rough guess: check if you accidentally enabled softproofing. I'm getting virtually identical results in ASP and Gimp when i make sure both use the same monitor profile. (Ubuntu here)

bingo!
Billion thanks spoilerhead, the softproofing was enabled
Now I only wonder when I stupidly switched it on. Updating from the B5Lite, I even did not know that such a feature exists.
I must cancel my yesterday bug report at surveymonkey.
