Does this occur everytime? Could you attach your system_info.txt?
comment:4 Changed 13 months ago by leper
Could you try to reproduce this in a debug build? That should give us some clues where it is failing.

Attached debug output. Unfortunately the integrated feature to attach gdb never worked for me (as you can see in the output), I also cannot run it under gdb myself.

(I mean I can't use gdb when the 0 A.D. pop up window asking what to do appears.)

Drivers for modern hardware are meant to support non power of 2 textures but most applications tend not to use them for compatibility reasons. So have a driver such as ours which has problems with NPOT textures doesn't break much and is presumably a low priority item.
From reading
http://www.opengl.org/wiki/NPOT_Texture
I found that our problem is more specifically a non multiple of 4 texture size. This causes issues with compression as mentioned on that web page. Using 16x36 worked when I tested.
