Screen Issues while playing Mario Kart Wii

[sauerplayer]

Everything seems fine on Mk wii menu till I reach the start of a race and while racing..., the top left quarter of the screen seems to blur without any reason
Idk why am I having this issue,  I have changed all Dolphin graphic options but Idk what is causing this, any ideas?
















same happens when ignore format changes is not checked, and fog is enabled or disabled.

Make sure ignore format changes is not checked. If that doesn't work you can try enabling disable fog.
