Hey ColonelVirus,
This could be a post processing issue. Would you mind typing the following command, ‘ShowFlag.PostProcessing 0’ into the command console to see if this fixes the issue?
I tested this issue on my end and am not seeing the same thing you are reporting.
Check to also make sure you Engine Scalability settings are at Epic, and your Material Quality Level is set to High. These options can be found under the ‘Settings’ dropdown menu in your main viewport window.
Thank you,
