screen flickering problem - Sony Xperia Z Ultra

So recently the bottom portion of my phones screen, about the size and place of the nav bar, has started flickering. The nav bar is disabled, I'm using pie controls, though I did test turning it back on and it did nothing. It's running CM12.1.
Can anyone help? Any idea what's causing this?

So about a quarter of the screen up there is now a flickering line, everywhere below that line now produces afterimages as what's on the screen changes.
Pretty sure it's a hardware issue, I can even see the effect during the CM startup animation.

[Q Issue with brightness going all over the place

Hi guys, I have a very strange problem that has been occurring over 3 different firmwares on 2 different S2's. If i swipe my finger over the top right hand corner of the screen (like where the time, battery %, etc. is) the brightness of the screen automatically increases to either half the brightness bar or 3/4ths, or sometimes 90% of the bar.
I have tested this on 2 phones in several different apps, home screen, etc, and even in landscape mode (landscape mode shifts it to the top left of the screen which would be the top right of the UI) which leads me to believe it is a firmware problem and not a hardware problem. However considering it was an issue on my brother's phone running stock KG6, my phone running Sicopats rom based on KH3, and his phone after flashing stock KH3 then on cognition 1.5.1, i am confused as to how all of these rom's could have this issue.
Is it because the issue hasn't been addressed? am i doing something wrong? please help me out guys i know this seems like a small issue but now that i've noticed it it's bothering me quite a bit
It's a Samsung feature. Sliding your finger on the status bar while in manual brightness mode adjusts the brightness of your screen.
I thought so too at first but its so unpredictable that I dismissed that as a possibility. do you know if there are any mods which disable this?

Second screen not scrolling when main screen is off

I just got this bad boy yesterday and now it seems that I can no longer scroll the second screen by swiping on it to access the quick toggles when the main screen is off. Last night I was able to, but today it seems stuck on just showing the time/date and notification icons. No matter what I do I can't get it to scroll to the quick toggles anymore. Anybody else have this issue? Any fix? I have the AT&T version if that means anything.
TIA
Figured it out. I turned KnockOn off and apparently that disabled the whole digitizer when the main screen is off. As soon as I turned it back on, my second screen started working again.

bright bar on top of my screen - android 5.1.1

Hello together
I have kind of a strange problem. Yesterday I got my new tablet (IRULU X1S) and it's a pretty neat thing, runs fast and everthing was working fine.
Then I have been using the chrome browser and let the tablet lie around. When the screen was darkening (because of idle) I turned the tablet and the screen tilted. Since then there is a bright bar on top of my screen (if I hold the phone upright).
When I tilt the Phone the bright bar stays at the same place, meaning the bar is now on the side.
Its almost as thick as the status bar and it's way brighter than the rest of the screen.
One could say the rest of the screen still seems "darkened".
What is really really weird is, the bright bar is even visible if I enter the phone "root" menu (pressing vol down und power). The top pixels seem brighter than the rest.
Is this a known Android poblem? It can't be a burn in, because it happened after tilting the screen and is there since then.
I tried to remove all apps that I installed and even factory reset the tablet. The bright bar is there in every screen, on the bootscreen and also in the "root" menu. Is there maybe a way to reset the phone to all defaults, e.g. putting a new OS on the phone? Because it has to be a software bug...
Thanks for reading and I hope you have some ideas how to fix this!

Green Display Problem

Sometimes when turning on my Display it looks green and with horizontal lines all over it. Screenshot doesn't capture it. It has been like that for a while but just got way more frequent. A reboot fixed it and i noticed now sometimes also just trying again to turn on the display sometimes fixes it as well as charging it while doing so.
Since it got more frequent theres also this high pitch sound when i turn on the display and the green distortion happens. I have no energy saving mode enabled. Anything i can do or do i need a new phone/ display if it stays like this?
It's a known issue I guess try to keep the brightness high, it happened to me some months ago but for some reason it's gone now. If you need to lower your brightness (ex at night) use some sort of app (like twilight) which actually puts a layer on the display (the screenshots are darker)

Netflix Black screen with Audio when i touch the screen...

Hello everyone, I just got my mediapad M5 last night, I was eager to watch the new episode of Better Call Saul, it streams in HD and all, but when I am watching anything, and If lets asy I touch the display to rewind for 10 seconds, or move the bar, IT GOES BLACK, if I let go my finger it plays normal.
I was reading that this may be cause by another app drawing over the display and the netflix app freaking about thinking someone wants to record it and take pictures of it naked.
But I disabled all the apps drawing over other apps, restarted, to no luck,
Anyone else gets this?
No one? really of all the 38 people no one can check?
I don't have Netflix installed and I'm not even 100% sure of your issue (i.e. when you touch the screen to rewind, it rewinds but the screen goes blank underneath the overlay? or it doesn't rewind and the entire display goes black)
It could be an app issue. If you have 'disable HW overlays' checked in Dev Options, that could cause such an issue. EMUI's battery optimization is pesky and could be an issue. You should have the app set to 'manage manually; in launch, you should have 'disable battery optimization' checked, if rooted you should use Titanium or Service Disabler to disable Power Genius (which is responsible for EMUI's aggressive battery optimization). Getting rid of Power genius solves various pesky issues with no negative effect on battery life.
OMG finally someone, thanks for your reply,
Its not a faulty device since I already tested my fathers M5 and it also has the same issue.
The issue is as you say, whenever I touch the device and it brings the netflix overlay it turns the background black, and when the overlay fades away it returns the video feed, but it doesnt pause, since the movie keeps playing and the audio keeps playing also.
The issue is that whenever I touch the display to bring the overlay controls

We are having a similar problem, but with the mouse cursor. This is with the MediaPad M5 with attached hardware keyboard.
As soon as I move they mouse cursor, the image goes black. The video keeps playing, you hear sound, but no image. Wait 15 seconds for the mouse cursor to fade away, and the display comes back.
Also, the last word from every subtitle line is missing, as if there is a text scaling issue where the text gets wrapped to a next line which isn't displayed.
