None of these things worked for me on version 4.26.1
I am not criticizing anyone or saying negative things to the person. If it worked for you then I’m glad it did, but to those still having the same issues. Here’s how I fixed my issues. Go to your base character check the categories for “Character Movement: Walking”, look for the Max Walk Speed, and if you created animation BP and animation Blend Space make sure that Maximum Axis Value blends with the Animations.
This is how I solved the shaky and blurry when my character moves backwards and sideways. So it may or not solve your issues so it’s best to try. Also I set my project to replicate movements so chances are this may not solve everyone’s problem Please do give this a try to see if this could be your resolution.
Here’s a picture how I solved my issues:
