Hello
I'm sorry to reply such an old topic, but I meet the same trouble.
When the fps is lower than 100 and move the main camera, the uifollowtarget seems to have a delay. The hudtext isnt in the correct position during the moving. And when the main camera stop moving, the hudtext can set to the correct position.
Lower the fps is, the delay seems more serious. The hudtext seems dancing when the fps is 30 TOT
Thanks.
