RE: Render Errors in OGL and Flipped Screen in D3D

Bad graphical corruption in certain areas
Find the following registry entry:
Add a new key (type String) and name it 'OffscreenRenderingMode'
Double click the new key and add the value 'pbuffer'
This may or may not fix the 'indoor white minimap' problem. No guarantees though!
Note: Pbuffer (Pixelbuffers) are an old 'experiment' that WoW started to use back when it was developed. They have since been replaced with Framebuffers, which is one of the reasons ATI hasn't included full support for them in the Linux drivers yet. Setting the above value to 'fbo' will switch the rendering mode to Framebuffers, which may speed up rendering on newer graphics cards.
