What's the problem? Describe what went wrong.

[Description here]
Screen mode changes from 4:3 to 16:9 if Wave beam is used and hits a wall

What steps will reproduce the problem?

In Phazon Mines (at least), Equip the Wave Beam and shoot a wall, the moment the beam hits the wall the video changes from 4:3 to 16:9 until start or map button is pressed. Other beams don't cause this issue. If you shoot a charged wave beam it doesn't happen either. (see the video)

Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too.
