Blurry dark box in Mario kart Wii appearing in top left corner.

I've been playing Mario kart Wii and on certain tracks like mushroom gorge, a large dark blurry box appears on the top left corner of the screen. Any one know how to fix? I'm using the latest version as of may 14 12:06 pm

It's been a long standing bug for a few years now. As I understand it, it's because of missing graphics feature in Qualcomm's Adreno GPUs. There's no solution for it currently. Hopefully, Qualcomm implements this feature in their future chipsets.

Edit: Thanks for the correction Josjoice. Smile

It's a missing feature in the driver rather than a driver bug.

Which feature is missing?

Hm... On the top of my head, it was dual source blending, but after looking it up it seems like it's actually Mario Kart: Double Dash's full-screen tint I was thinking of. I'm not sure if it's the same for Mario Kart Wii or a different one. Might be the same.

You are advocating forks. But if the fork does fix the problem and the official builds don't, it's not against the forum rules.

master does have logic ops, it's just that it doesn't work on certain hardware/APIs. Notably, logic ops don't work properly on Windows 7 when using Direct3D 11. I'm not sure what the restrictions are when it comes to Android devices, but I guess weihuoya has implemented it in some different way that has lower requirements (and possibly lower accuracy? I haven't actually checked it out).

"Use this fork, it's better/faster/stronger"

Against forum rules

"Use this fork, it specifically solves this issue that master has"

Fine
