    I have Nexus S i9020 and I have this bad problem..
    It's started when I flashed AOSP ICS Brainmaster's Mix.. When I locked the phone, I had a strange yellow-green flash on the screen.. I tried flashing different kernels - no effect.. When I tried playing with Voodoo colors - no effect.. The only "semi-cure" was: if you return to "Stock gingerbread colors" that damn screenflash was seen only on the contour of clock and "that slide thing to unlock the screen" (don't know how to name it in english=))..

    I thought that it was just the bug of the ROM then.. But when I flashed CM9 latest alpha everything remained the same.. I also thought that it was just a bug of the ROM..

    But now I flashed ICS OTA after the downgrade to stock 2.3.6.. And the result is the same to switching to gingerbread colors in Voodoo app on AOSP old ICS ROMs.. I still have the screenflash on the contour on the lock and that "slidething"..

    It's really annoying now as I'm starting to think that it is a hardware issue.. But all other functions work just perfect, not any single issue with the screen.. I haven't dropped my phone, haven't kicked it or something (bought it in June)

    Can anybody help with this please?

    I tried playing with "Transition animation scale" and "Window animation scale" in Developer Options.. Setting window animation scale to 0.5x solves the problem.. But it turns off CRTscreen fadeout.. So there is something wrong with it on my phone.. I don't want to loose it, it's beautiful..

    P.S.: there were some similar threads here, but I haven't found the cure..

    I'm experiencing the same thing too. The greenish-yellowish flashy screen right after the TV animation when the screen turned off. It's irritating the heck out of me, thinking someday the screen will just give. I think it may be an issue with Voodoo colors. I'm running stock ICS 4.0.3 as well, with GLaDOS kernel. I tried to reset Voodoo color to 2.3.3, the flashy thing doesn't go away. If anyone finds an explanation or a remedy to the problem, I would really like to know. Thanks!

    I have this issue on my Nexus S, stock 4.03 with Matr1x kernel. I think it's an issue with ICS on Nexus S, I had this issue on my Nexus S when I used the Cyanogenmod 9 alpha builds. Let's just hope we get an update to fix all this garbage...

    This is due to Voodoo Color set with custom values (either by custom kernel default or the Voodoo Control app). Having stock colors fixes the problem.

    I went back to MIUI (GB version), Trinity kernel, with Voodoo Color settings. The greenish flashy thing happened there too, but in MIUI in Display >> Advanced Mode setting, you can set the Light Level To Dim to 20 (default) and it no longer flashes the greenish screen before it turns off. I'm hoping the custom ICS ROMs like CM9 or MIUI ICS will have this ability to change Light Level To Dim.

    it seems to only happen when there is a live wallpaper or something moving on the screen. If you have the keyboard open with the curser flashing it will happen as wel, even when you turn the device on the lockscreen it will also do it. if you have a static wallpaper then it wont happen if you're on the home screen. Thats as far as i can tell on how to recreate it.

    This happened to me since alpha builds, I think this is just an issue with ICS. I had stock everything ( no voodoo no custom kernel, just rooted) and it gave me this irritating flash. Maybe this will be fixed eventually by Google or when someone on XDA realises the issue.
