Sliding two fingers on the screen causes jitter.

Zen Master I
Rooted: No
APP Name: All applications that require two simultaneous touches to control.
Model: ZE620KL
RAM: 4G
Firmware/APP Version: Tested on several.
Frequency of Occurrence: Every time the user uses two fingers on the screen.

Hello, folks. I bought my Zenfone 5Z (4GB/64GB) recently, specifically to play some games that other devices that were within my budget wouldn't be able to handle. But I'm disappointed with a detail that, although it looks small, makes a huge difference to the gaming experience. Every time a game requires two fingers to control (usually first-person and third-person shooting games), the touch sensitivity doesn't allow me the precision I need for such games. I slide my left thumb on the left side of the screen to control the movement and my right thumb on the right side of the screen to control the aim, as the game requires. The problem appears when I try to aim while running. What you don't notice when you slide your fingers quickly, when I slide slowly (for greater accuracy) the screen doesn't respond as it should, generating a jittery stutter. To test more thoroughly, I downloaded the MultiTouch Tester app from Google Play. During the tests I was able to see that the problem happens when - specifically - two fingers are used. Not with one, not with three or more. I'm in the stable version of Android 10 that I downloaded from the official Asus website in my country. I was only able to update my device this way, since when it arrived (with Android 😎 I couldn't find firmware updates available. Anyway, I found this problem even when I was using the Android version that came from the factory on the device. Thanks in advance!

Since the zentalk forum has changed I have trouble reporting a bug 😂. how are you about this bug? Until now there has been no software improvement regarding the touch panel issue. 
I hope this problem is resolved soon, because the Zenfone 5 device does not experience this problem where the LCD hardware used is the same.

Hey, Jonny, you're back!
Moderators said it'll be fixed in the next FOTA. (I hope they are improving the same issue we reported, there are some communication problems due to the language barrier. xD)

I hope so, because in every Zenfone 5 firmware update there is always an increase in the touch panel driver while the 5z never
