The bug is still present.

Sagawa investigated the problem and found the followings:

* DX Library 3.10f/3.11 (which is used in WOLF RPG Editor 2.10) expects that
IDirect3DDevice9::UpdateTexture() updates **ONLY** the dirty portions (recorded
in IDirect3DTexture9::LockRect()) of a texture in the font cache handling
* d3d9.dll in Windows does it, but wined3d updates the whole texture and it
breaks font caches
