Wall with light effect triggering the artifact.
On game Shawdow Warrior, with Southern Island chip, drivers from this PPA:
https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers
Experienced both on Ubuntu 14.10 and, after upgrade, on Ubuntu 15.04.
Some special effects trigger a visible artifact on triangle primitive
boundaries, probably, see screenshot attached. With fglrx, the issue is not
present.
It seems the problem is on some post-processing shader, because, as can be seen
in the screenshot, the visible triangles does not respect the boundary of scene
objects, and if I move the mouse, they are fixed relative to the screen.
Running with the following env var (otherwise the game is unplayable slow on
current video settings):
R600_DEBUG=sb
