Does anyone know why my viewport looks like this?

I can not figure out why my viewport looks like this. It is ok if I use 4.19 but anything higher and this happens.

Have a look at the nVidia control panel and search for stereoscopic mode. It’s more likely enabled.

Looks like you have some sort of stereoscopic 3D rendering enabled. Not sure where you set that, perhaps it’s a post processing volume?

Hi,

Check your PostProcessVolume>>Lens>>Chromatic Aberration. It’s most likely turned on.
