Example of my problem

Maybe it has something to do with the fglrx graphics driver?

Comment 3 Olav Dahlum 2011-06-09 16:06:47 CEST

Did you try with the vesa driver etc?

From the screenshot in comment#2, it looks like chromium-browser is the browser showing the weird colours, right?

No, only the screenshot is showing the chromium-browser. It's made using Firefox.
The problem seems only to occur on my notebook. My desktop computer shows normal colors even there i use the same graphics driver.

Ah, I see.

A shot in the dark, open about:config in firefox, and set layers.acceleration.disabled to true (double click it to toggle false/true), restart firefox, then try again.

Scratch my previous comment, try tweaking the gfx.color_management.mode settings:

Ok das hat geklappt. Wert auf 0 gesetzt und schon sind die Farben wieder normal.

Ups sry wrong language xD.

What i wanted to say was that it worked for me. Value 0 and the colors are rendered correct again.

Comment 11 Ahmad Samir 2011-06-09 18:46:43 CEST

Great :)

(If other users report a similar issue, then it'll be an indication there's something globally wrong somewhere and not just specific to your setup/box, in which case we can reopen this report).

Excellent, you worked it out.
