Emulator

This bug have been here for ages in upper left corner of the screen
it's for both OGL and D3D plugins, and it seems it's an upscaling bug
cause when i playing native resolution that effect covers all the screen
here's some screens
Of course it's ZeldaTP

not sure it's the same issue, but look's very same if you ask me
DeBlob requires LLE to go Ingame
I think there's much more games with this issue
