Description Ernst Sjöstrand 2010-02-08 12:46:23 UTC

There are a lot of rendering issues in world of warcraft on mesa+radeon but this one looked somewhat more straight forward than the others.
So this loading screen is distorted in sideways and mirrored across the diagonal.

This is how it should look:

Card: Radeon 4770
No compositor running.

Wow, now there's no rendering errors at all when using the DirectX backend!
Veeery slow though...
