Graphic Artifact

[SDN]

Version:
Ubuntu Gnome 14.10
Manaplus 1.5.1.31 Binary Version (and some other clients before this one)
AMD Athlon II X3 (sometimes I unlock the 4th core into Phenom II X4), Nvidia GTX 550Ti GPU, Realtek HD Audio.

I found this artifact once a while, not often--even rare, but always occur at the exact same spot in Swamp and Graveyard area. It's usually disappear after restarting the client. I thought this is just an opengl driver problem (or even hardware defect, although no problems in other 2D/3D games/apps), because I remember never had this artifact in software rendering mode. But, I'm not really sure.

I cant totally sure is this is out of video memory or some kind of issue in driver.
But you can avoid it by disabling option in settings, performance tab with name "enable texture atlases". It located almost at end of settings page.

Oh, i forgot to tell you that my graphic card ram is 2GB. I have test it with GPUMemtest and everything works good. So, perhaps this is just opengl driver issue. Anyway, thanks a lot. I'll make sure to disable that option..
