The playback head freezes and disappears Premiere Pro v.22.0

According to the first feelings of working in Premiere Pro, I noticed how much the game head on the timeline has become more responsive. Previously, when you click on the stop, the game head jumped a few frames ahead. It's great now.
BUT I also found a lack of display and fading of the head on the timeline when using the JKL keyboard shortcut. Not very correct work occurs when the viewing speed of the material increases. Freezes and takes time
