Bug: Being pushed by diagonal walls can cause the camera to shake, flicker, and show black bars moving across screen

Interacting with diagonal walls can make the camera freak out, or prevent the player from moving in valid directions until they stop and reset their movement. Requirements:

• Omnidirectional Movement (using an analog stick, rather than keyboard)
• Subpixel Movement active (smooth camera scrolling in quest properties)
• Walk with the control stick held at an odd angle (not any direction8)
• Have diagonal walls push you along a direction8 path

If subpixel movement is not enabled, you can still encounter the bug where valid directions are blocked:

• Walk with the control stick held at an odd angle
• Face direction 6 (given in direction8 directions)
• Hold control stick between direction 6 and 7
• Have diagonal wall push you direction 7
• After passing the end of diagonal wall, you will be unable to walk direction 0
