Render is extremely stretched vertically?

[klj92nh62]

For some reason, whenever I render out the scene, the render is turning up extremely vertically stretched. It was rendering fine before but now it's looking very strange. The object is a skull with a frosted glass material applied to it against a dark background.

Here are the settings. Frame buffer on the left, common render settings in the middle, actual scene on the right.

What can I do to fix the stretching?

The render settings look sane. Perhaps check the camera. Maybe try creating a new camera, especially a VRayPhysicalCamera rather than a Max Physical Camera.

Ended up fixing it by switching the renderer to scanline and back to V-Ray
