window display bug jerks

Hello, I just installed vital version 1.5.5 and when I open Vital in Ableton Live 10.1.43, the Vital display window jerks (blinks constantly); I’m on a mac Pro 2x 3.33GHz 6 Core Intel Xeon, ATI Radeon HD 5770 1227MB graphics card and my Mac OS is High Sierra 10.13.6, do you have an explanation?

Do you know if you might need an update to your OpenGL driver or maybe your graphics card?

That’s the only thing I can think of sorry, unless maybe your RAM is maxed out? ( But I wouldn’t think so)
