Mouse sensitivity increased significantly since 1.14.3 pre2

Between versions 1.14.3 pre1 and 1.14.3 pre2 mouse reacts a lot more sensitive. Either in a fresh 1.14.3 pre2 world or converted from pre1.

I only noticed when upgrading to 1.14.3 since I usually only play full releases. Then I did some tests and found the issue to be occuring since 1.14.3 pre2.

More people reported this when 1.14.3 launched:
