Slow response to climb with bugged altitude. Starting with the install of V16.0 or so. I've noticed that when using AP, I bug an altitude and,(my default climb rate 800ft/mi) the aircraft climbs within 1000 to 1500 ft of bugged altitude then the bugged altitude shown above the altitude indicator disappears! Climb rate slows to 200-300 ft/min. It takes forever to finish the climb to the bugged altitude! I've had numerious request from ATC when flying in class B space to speed up the climb. I turn off AP and, complete the climb manually. My equipment configuration is: Dual HDX displays, Garmin GNC355, AP button panel, auto trim, arinc 429, HDG-BARO-ALT panel. This aircraft flys regularly in IFR conditions. My voice alert is set to100 ft of target altitude . Looking for input to solve this slow response and, explanation of why the bugged altitude disappears from ALT window. Thanks!
