There is a weird blurring effect that's not being picked up by OBS, Discord screen sharing, or any screen-shot application. However we've verified it on multiple separate computers running a fresh install of 1.13. It's causing motion sickness and it's generally upsetting.

Please see the following links for independent phone-video recordings as none of us can seem to record it with computer software.

We've tried any and all video settings to disable this, nothing seems to be working.

It's extremely apparent on the lowest quality settings when you have the biggest difference in pixel colors. This seems to be some sort of additive blur that only exists in Minecraft.
