Strange video artifact problem

The graphic has a shadow. This continues into X once that starts. Example: http://cooklikeyourg...es/Screenshot.png It seems to come and go, as though it might be sensitive to temperature of the system. How do I research this? -- Drew

(Please note that if there are obvious issues with that image that I'm not seeing (other than the fact that it's not Aqua), I'm going to claim that I've been sitting at my computer since 7:30am straight, working, and I'm tired.) ;-) -Mike "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." - Benjamin Franklin, 1759 Historical Review of Pennsylvania

If I'm seeing video problems that are not visible from a screencap, does that mean it's a hardware problem? -- Drew

I'd be thinking its a hardware issue with either the screen itself or the "cable" between the video card and screen. And Yes I know you say "The Cable between?", yes the cable between. Its now typically a ribbon-esq style of cables and you might be seeing degradation or perhaps the connector to the video card isn't right some how. In any case, if you can boot up another OS and see what happens (you know Windows is required for troubleshooting don't you). Good luck. As to where to look into this... lookup the hardware itself and add on your problems without any OS specific terms. And if you could take that awesome camera of your and take a shot... I think you'd be able to get more feedback.

That is, the apparent-sharpness of the black/white edges prolly goes to iMac, but: there seem to be more 'elements' (lines, curves) -per-character to yours! (iMac default that is; dunno what else might improve on that. Yet.) I expect that Peter and others have some views on which be the bitchinest fonts ... to use a technical term which only we epicures know. Posit: Apparently the eye/brain weights the really-sharp edge contrast higher than the actual %linear-fill of a given character ?? (I still need to sort out preferred sizes, font choices and other trivia which, together gilds the lily to a fare-thee-well. Poco á poco.)

Post #303,629 by Ashton 2/4/09 9:51:08 PM Reply	Most illuminating - (Saved for other comparos) Zoomed ridiculously, clearly the contrast Is higher for the 'assembled pixel-blocks', but the smoothed sample reveals its method: can see the use of color to smooth via illusion; clever lads.. Smooth beats highest-contrast, yet from one angle, technically: via added-fuzziness! This font display shows it perfectly. Thanks

Those is just the default fonts that come with Gnome. http://www.gregfolke...nt-Selections.png And Remember... these are taken at 72dpi... being the default for the screen capture stuffs.
