[Windows-XMB] Dolphin displays texture maps when loaded w/ thumbnails

I noticed a weird bug and manage to reproduce it fairly easy. But I was wondering if the same happens in other setups/OSs. When I load from the XMB a Dolphin game with a thumbnail image (doesn’t matter if it is title/boxart/snap), the core displays one of the texture maps instead of what should be displayed, even on games that run normally (when started from the XMB without a thumb image, or from the history, eg.).

Some examples (click on the image to see the entire emulator window):

Even Super Mario Sunshine, with the thumbnail from the repository (and the 512px width limit) displays the same problem.

If someone could try to reproduce the steps to verify if it is a proper bug, I would be grateful.
