--- Comment #29 from Florian florian@fkoeberle.de 2010-07-03 12:46:53 --- I have got the terrain editor working for me:
I set the registry key HKEY_CURRENT_USER/Software/Wine/Direct3D/OffscreenRenderingMode to backbuffer and started the editor and opened at first the terrain module. The editor froze as before but was still printing the following two lines every second:
fixme:d3d_surface:fb_copy_to_texture_direct Doing a pixel by pixel copy from the framebuffer to a texture, expect major performance issues err:d3d_surface:fb_copy_to_texture_direct Texture filtering not supported in direct blit
Then after about 10 or 20 seconds the editor became responsible again, but the ground texture was broken in the area which is visible at start. Moving around the view fixes the ground. It is possible to place stuff on the wrongly drawn ground.
Afterwards I tried it again with the registry key set to fbo and with strangely it didn't freeze and the ground was correct from start on.
I tried it multiple times again without that registry key set and it continued to work. In other words: I can't reproduce this bug anymore even with my old setting...
