Hi !

I think the bugs description is wrong :
 - I don't think the problem is with the video driver because the same happens 
with a S3 card. I guess the problem is an incompatibility with mesa.
 - The " little problem " makes the games unplayable, because the map is no 
longer displayed :-(

There is a workaround. It looks like the problem is in the selective redrawing 
of the map, in uLand.pas :
| procedure UpdateLandTexture(Y, Height: LongInt);
…
|        begin
|        glBindTexture(GL_TEXTURE_2D, LandTexture^.id);
|        glTexSubImage2D(GL_TEXTURE_2D, 0, 0, Y, 2048, Height, GL_RGBA, 
GL_UNSIGNED_BYTE, @LandPixels[Y, 0]);
|        end
if I hack those lines to make them redraw the whole map every time (by forcing 
Y=0 and Height=1023), the problem no longer occurs. Maybe it's a bug in the 
game triggered by the OpenGL implementation ?

I will cross-post this on the game's forum.
