I've noticed this occurrence for a long time, but never thought to ask until now.
I have this issue in my Impact games where there are occasional flickers of 1-pixel wide black lines that span the game frame.
These lines usually flicker near the extremities of the canvas as I walk along my map, both horizontally (near the top) and vertically (near the left). They seem to line up with the edges of my map tiles. They may be black because of the black game background. This occurs in Weltmeister too.
Sometimes if I stop moving in my game, I can get the black line to remain in place on the map. So it's not a truly random flicker -- it's tied to movement against the background.
It's strange because I don't notice this on any of the Impact samples, from which I derived many of my games (Pong, Jump 'n Run, Drop). The originals all render as smooth and flawless.
Is there something I'm doing wrong in my code, or is there some other explanation for these flickering lines (i.e. JavaScript engine, my nVidia drivers)?
Thanks!
System info:
Ubuntu 12.04 32-bit, Unity DE
nVidia GeForce GT 240
nVidia 310.14 drivers
Firefox 21.0 (Mozilla Firefox for Ubuntu, Canonical - 1.0)
(Note: I've noticed this issue over several versions of my operating system, video card drivers, browsers, and even computers)
Update 1: I tried to take a screenshot to post on here, but as soon as I opened my screen capture program, the black line I had paused disappeared. Very strange.
