Windows – Weird “smoothing” effect in Windows 8 app store

Can anyone tell me what's causing this weird smoothing effect in the Windows 8 app store? It's the only screen (I've found) it appears on. It doesn't happen on the Start screen itself.

Here's what it looks like:

My first thought was my graphics card. Maybe AA messing with the font, but I've set everything to default (aka "Application Controlled"), and nothing changed:

I have an ATI Radeon HD 6870, and am running the latest drivers from AMD. Anyone have any idea what's causing this?

Ok, figured it out. After I've enabled Anti-Aliasing (either MFAA, MSAA or SSAA) on my graphics card for a particular process (e.g. MassEffect2.exe) the App Store (and all Apps, except the Start Menu) have this effect.

So basically, for whatever reason, the AMD Catalyst program is applying AA to the App Store once it's been used by a game. It does this until I reset my computer. Clearly the App Store must be using D3D, even though it looks two dimension in its presentation.

So I guess it's some sort of bug with the AMD Catalyst software, but whatever the reason, at least I know what causes it, and how to fix it!
