Agreed, the U bend mounting plate acts as a spring. Remove any form of springiness in the whole system. Just push and pull on the toolhead without moving the stepper motors. If it moves you need to fix 5hat first.
My guess is that when the hotend moves, the bowden tube starts swinging to and fro causing the U profile to bend in the same motion. If it's not rigid enough you'll see it in the print to varying degrees.
Two screws is not necessarily bad, it depends on the materials used, thickness and rigidness, and the two mating parts should have a solid, flat surface and maybe a notch for alignment and to prevent any lateral movement.
I use an 6mm aluminium plate on the x carriage and a 3mm mounting plate to be screwed into the 6mm plate tapped holes using 3 bolts. The hot end mounts to the 3mm plate. That way I can easily mount different toolheads. I also have a 10 pin connector on the toolhead for power and sensors. Eventually I'd like to add a toolchanger at some point. See my NFAN build in the signature.
Also make sure the belts are tight.
