Even I faced the same issue, and this problem is faced by multiple users. Just check the telegram channel, so many reports on the same problem.
Mine the bottom middle part of the screen sometimes touch not registering like scrolling but again if I click any apps it opens. Only this problem is related to scrolling.
I have got the replacement of the phone and now there is no issue.

i think thats software issue in miui in android 11.not in poco x3 pro. in all xiaomi devices. i found one solution. i dont know it work or not. let me explain:

Turn off MIUI optimization > give restart >Turn on MIUI optimization < give again restart.... Problem solved...yku can find miui optimization in developer option
and if u dont find optimization in developer u should:

Tap "reset to default values" in developer options a few times to view the miui optimisation toggler. You'll have to give permissions to apps again though.
i test it for an hours and share my result if it work or not. every body pls share their result. 🌷

3 things here
A) The problem is not for all phones i guess, faced the issue on Vayu version and my replacement phone was Bhima. In Bhima no problem.
B) If you think its due to MIUI optimization then i dont want to activate miui optimization then its not the right solution.
C) I have seen some people reported the issue because of popups that they allowed in some particular applications like Teams, etc

There are custom Roms now. Some ways to distinguish the source of issues.

1) If using custom Roms other than stock MIUI or by Xiaomi.eu and the issue vanished

1A) If your MIUI is not up to date --> first update to see if it's fixed, sometimes Xiaomi already fixed it, sometimes.
1B) If your MIUI is up to date, it's MIUI rom problem. --> Find Xiaomi

2)
If custom Roms still present with this issue, there is at least 3 possibilities

2A) Hardware issues (either universal or unlucky faulty devices) --> Find Xiaomi
2B) Stock firmware causes. Even custom Roms most likely will use stock firmware, so if there's problem in the firmware, most custom Roms will be affected. --> Find Xiaomi
2C)
Android 11 compatibility issue. Some apps are outdated or no optimization. Issues is to be expected. --> Report to the App

This is not all, only think of these at the moment.

You can see most of the solution is Find Xiaomi, so just complain to Xiaomi customer service. This is the easiest way. But first follow 1A) because they will very likely tell you to do that. 2C) will be the answer if they just want to turn a blind eye.

Another way is turn on ADB debug in developer option, connect your PC, use ADB command as
Code:
adb bugreport C:\Reports\MyBugReports.zip
If it gives error, it will tell you the command to pull out the file from your Android.

See this link for more information.

I got till dumpstate_board.txt, after that what I should search for?

Open the "dumpstate_board.txt", then "Search" the text file with the key word "huaxing" (without the quotation mark)

If it did not find anything, it's most likely you have "tianma".
"Search" the text file with the key word "tianma" (without the quotation mark).
