kobo libra color

[zxcvcxz112]

When using the screen to turn pages on the Kobo Color, sometimes there is no response on the first tap, and on the second tap, it turns two pages at once.I believe it's a problem with system. When I use KOReader, I never encounter this issue, and when I use the physical buttons, there's no problem either. However, the issue occurs when I touch the screen.
