[driver bug]Large textures vanish with distance

[Skadoomer]

This exsists for all builds i'm pretty sure. I was running 0.9.5 and 0.9.3 when i saw this issue. I have a very large texture (1024 X 1024) that has a section of it dissappear when the player moves far enough away from it. Here is a screenshot:


I've isolated the issue in thistest map. Ignore the pink in the texture, i have a custom palette i was using.

Works for me. This looks like your graphics card is creating an incorrect mipmap.

Please do the following things:

1. Change the texture filter settings and check whether this has any effect
2. Post the startup log you get by adding '+logfile log' to the command line.

weird. Going through the filtering options, it prefers bilinear. However, when circulated back to trilinear (the default) it acts fine. Weird. Thats what i get for using intels onboard video.
