Non wiki settings used, reset your config and only apply wiki settings.

Also please fill out the system configuration section. Otherwise we can't even know if this report is related to other reported issues. Different OS/hardware combinations will have different results.

I added my computer specs. I'm not sure what are the wiki settings i tried with the settings mentionned on the lbp page of the wiki it didn't work. I tried with full default settings didn't work. I tried a lot of differents settings nothing worked except:

Using Opengl
Using a nvidia card
Using Strict rendering mode but it create shadow issue and disable resolution scale. (default resulution scale without strict rendering mode still have the issue btw)

Does enabling "force hardware MSAA resolve" do anything? Check the advanced tab.

No same issue only change i noticed is the perfomance (~15fps instead of 30).

I noticed now that when i launch the game with aa enabled this red line show up in the debug:
E RSX: Your GPU does not support alpha-to-one for multisampling. Graphics may be inaccurate when MSAA is enabled.
