@AtlLED Oh, sorry - I can assure you that the screen is solid black and solid white (no vsync issues), and can additionally reference you to the underlying low-level code (SDL2's vsync-waiting update and GTK's GdkFrameClock for two different programs). Others have reported seeing the phenomenon, albeit with different patterns (they aren't necessarily consistent between people looking at the same screen; I have a really small sample size, though).

| Oct 26, 2013 at 13:20 | comment | added | Atl LED | @Atash Any update? Again you are likely seeing the pattern because of the way monitor is strobing, not because of any artifacts in your eye. | |
| Oct 21, 2013 at 20:51 | comment | added | Hurda | Are you strobing LCD or with LCD?? I bet you could not see that while strobing solid material with strobe light. You might see wiring of your LCD... | |
| Oct 21, 2013 at 15:33 | comment | added | Atl LED | I have actually experienced something similar before. What are you using to make the strobe? You can run into interesting patterns when you start strobing near the frequencies of your monitor (flashing refresh down as it's drawing). I'd also make sure it's not a programming effect. What is the difference between what you see and what other's see? | |

| Oct 21, 2013 at 4:47 | comment | added | user | @Memming Other people see the patterns as well, although not necessarily the same patterns I'm seeing. | |
| Aug 11, 2013 at 22:32 | comment | added | user | @Memming Info added. This is just a personal project, so all info I have is just from myself at the moment. -.-' It's really hard to count these things without getting a bit dizzy. | |
