Hey guys,
Any of you having a screen flickering problem when displaying grey?
Here is a link to someone with a similar problem (and an example image).

On the W510 do you know if there is a simple solution to this problem?
Thanks.

On a releated note: I did notice some backlighting uniformity issues when dragging the image around. The bottom half appears quite a bit lighter in colour when near the center of the screen, and darker when near the far left or right sides of the screen. On the other hand, if I set that image as my desktop wallpaper, tiled, and minimize all windows, I can't really see the backlighting uniformity issue. So it could be some weird alpha-blending issue, perhaps?
Now that you mentioned it, I downloaded the image and opened it with windows live photo gallery. There is less but still noticeable flickering when compared side-by-side with the image loaded in Firefox 3.6.
I do not notice the uniformity issues when moving the image around.
When the image is set as the wallpaper (tiled) my screen is going crazy with the amount of flickering happening!
