Faint ghost images can appear with as little as ten seconds of display. I wasn't really aware that screen burn-in also affected LCD screens, because I had never seen that on any display before. I wasn't expecting that on something that is branded as the highest quality display on the market.

This was a known problem on some Macbook units in that generation (including my own) depending on which of two manufacturers made the panel in your system.<br /><br />The effect is tied to how long an image was on the screen, so lots of stuff flashing by transiently wouldn't necessarily clear the ghost of something that sat for a while.<br /><br />If you bring it in to an Apple Store and show them, they'll run a standardized ghosting test, and replace the monitor for free (as the original is accepted as defective) if it's bad enough.

I've seen this occur in a Dell LCD monitor (produced in the early 2000's), but the ghosting wouldn't last more than 30 seconds. I've also seen this on a "big" (somewhere between 40 and 60 inch) LG TV. It was one of those "smart" TVs, probably produced some time after 2010.<br /><br />Anyway, just my thought. lvernsnoreply@blogger.comtag:blogger.com,1999:blog-3019054489127059271.post-1662890228517749122016-01-11T23:07:33.594+01:002016-01-11T23:07:33.594+01:00lightdm with nouveau on Debian wheezy would (I pre...lightdm with nouveau on Debian wheezy would (I presume) fail to load the background, and instead show a collage of pixmaps or blocks of rendered text from the previous boot. You're maybe seeing the same bug on a Mac, where alpha-blended grey was supposed to be composed over some buffer that was not initialised?<br /><br />Obviously it raises serious concerns about the security of NVidia graphics chipsets, *and* the nouveau driver; that this malfunction was even possible suggests flaws an attacker could exploit deliberately (and probably see a lot more).
