Emulator

What steps will reproduce the problem?
1.Run a game in window mode
2.run a game

What is the expected output? What do you see instead?
for 1.See something, strangely there isn't a window like ever with the game, i can see only a white screen inside the main dolphin window. The only way to see something is turn on the fullscreen option
for 2.a lot of games (for example monster hunter 3) have some new problems about audio. The emulator seems unable to manage the audio, i can see the "in village" music where i left the gona village (for a brief period). But this thing never happend before. Only the music channel seems to be affected by it in the games i played. Like a "tail" of the previous music

problem?
