viewing before image has different colour temperature and tint

[Adrian30215284to5e]

When I press \ to view the image before changes it shows the image with a different colour temperature and tint even when the image has not been edited.

It's only an issue for my most recent import and started partway through editing.

I have tried resetting the develop settings and also tried the Settings > Reset All Settings option.

Settings > Copy After's Settings to Before fixes it and so does Swap Before and After Settings, but I don't want to have to do that 500 times plus I'm sure there must be a better way.

Copy Before's Settings to After does nothing to either image.

I assume it's a setting but I have no idea and couldn't find anything online about this.

Seems to be a GPU-related bug. See this previous thread:

Thanks,
Disabled GPU use and it is fixed.
