why is the bottom part of my screen (u20i) unresponsive on custom roms?

i've tried all cm7 roms gingerdx, arcmini, sonystyle etc. the bottom part of the screen is unresponsive on some menus. I know it's not a hardware problem cause it works on some menus. for example when I type using the se stock multitapping thing it works fine but It 's unresponsive on dialer on camera on music, etc. I tried custom kernels but still the same, I reverted to stock kernel and rom and it happens only on some apps downloaded from market (sketcher is a good way to see this, sketches all screen except the bottom part). what do I do? I can't live with unresponsive screen. I can't even use dialer without sliding the keyboard. I am currently running minicm7 pro v19
is this the touchbug mentioned on the devs section?

[Q] Touch Screen Issues Gionee P6

Hi, recently I started facing touch screen issues.
My touch sensitive buttons aren't responding and sometimes the lower part of the touch screen is unresponsive. That is fixed with a gentle squeeze and a lock and unlock. Sometimes the touch behaves as if I'm using two fingers than one (scaling when trying to fast forward video using one finger )
Sometimes the entire touch screen goes unresponsive which is fixed with a lock and unlock. The scroll becomes dead slow too sometimes. Again the fix is the same.
I'm not sure if this is a firmware issue or hardware issue. The rest of the touch works fine.
I'm using a Gionee P6
I tried to trouble shoot using the secret star codes but unfortunately the menu is in Chinese for this device.
If someone could help before I send it in for repair which will take a long time I'd appreciate it
EDIT : I Was able to use the touch screen testing from the diagnosis hardware menu and there are no dead points. Every part of the touch screen responds. Except when I actually use them in Android

How to fix ghost touches on a FTS Poco running Pixel Experience?

I keep getting ghost touches just to the left of the notch (which pulls my notification shade down and occasionally opens the clock)
My phone is running PixelExperience-20190722-1316-OFFICIAL and has a FTS touch screen
I'd prefer a method that wouldn't force me to factory reset/risk my data. Thanks in advance!
Edit: forgot to mention I've tried multiple methods from YouTube videos before I made this post, including turning off 3-finger-screenshots
optimus drunk kernel worked for me, i have fts too.
Most likely you wont fix this by software i tried for 8 months. Only way is to change your screen. Read this thread

Optimus drunk improved it by little bit but didnt solve it
I had same problem so I was forced use Miui because in Miui statusbar not pulling down. Now replaced display from Aliexpress and working perfectly, no ghost touch, no touch lag and I can use PE again ?

moto g5 plus touch issue

i have been experiencing touch failure on bottom screen just above navigation buttons like a straight row in my moto g5 plus. which makes me like unable to give a space between when i'm texting. But sometimes it works for a couple of seconds and goes off. And sometimes the whole screen become unresponsive too and then i have to lock the phone and open again one to three times to make i work. currently it is running on pixel experience+ A10 rom. Is this issue occur because of i installed a custom rom. somewhere i saw that pixel experience have some touch failure issues like the users have to lock the phone and open it again just as i do. if it is a software prob maybe i can solve it by flashing the stock rom again . i'm a complete noob i need some serious help!

Touch freeze issue

Hi does anyone have a touch freeze issue if a wide touch is given to the screen.
I have this issue. I play pubg mobile with 4 fingers claw setup and whenever my fingers touch a wide surface area the touch just freezes. It is really annoying. I am not sure if its a problem with my display or if it is a software issue. Does anyone else have this issue??
Just test this- In any webpage in chrome try to scroll up and down by swiping with the whole of your index finger and see if the touch freezes or not.
Please check it and give an answer. I want to know whether its an issue with my device or a software issue.
