[Bug] Jerky scrollbar in App Drawer

[Anderhar]

On the device with 5-inch 440 PPI screen running Android 11, the scrollbar slider in App Drawer moves jerkily, depending on the amount of applications, number of columns, and row height.

Since Lawnchair 12 shows exactly the same behavior, here is my recording of how it looks like there (note how the slider makes one "jerk" at the beginning of the movement and then goes off-screen at the end of the bar).
