re your hw overlay issue
I'm not an expert but no one else has replied so will tell you what I know...I have the sgh-i747 running cm10 & kt747 kernel...I've read about hw overlay issue cause was having issue with setcpu frequencies not staying at what I put them and on xda or rootzwiki they said disable it...freqs started staying as what I set them but it got hot cause I was Max oc all the time with aggressive governor...used undervolt in custom kernel. Lowered oc freq and use ondemand governor and phone stays cool and battery lasts longer

how to deal with screen flicker ?

Hi. i have my GS3 for a while now and i just noticed that if i am loading a page on the internet, my screen flicker on the white page till the page loads regardless of what is the brightness.
i figured my GS3 has a problem with white color " hardware issue "
so i downloaded many screen test apps that display full colors. and my screen didnt flicker displaying any.
so i came to notice my ficker only happens when the phone is busy loading something.
i tried to tick the option in the developers option for the screen overlay ? it did nothing .
can anyone help ? figure out what is the issue ? i really dont think its a hardware issue.
i tried different roms but no luck :/
+rep for helps and suggestions. ty
so ehm. am i the only one ? lol sheesh
Can't say I've noticed any screen flickering, but then I use dolphin browser.
ive noticed this the last week or so but not on the white page. Its flickering a little when i go into the bookmarks page. Dont know whats causing it, never used to happen.
Is it real flicker or more like black boxes appearing all over the screen?
If the latter, make sure neither your Cpu nor Gpu is overclocked or undervolted since the issue usually arises with Gpu calculation errors due to overheating (improbable) or voltage problems

Dude, its most likely an incompatibility issue with the custom rom ( am i right? ) you are using. I had the exact same issue with the dolphin browser on paranoidandroid rom. Just install chrome, it most likely is compatible with most of the roms out there.

[Q] Text flickers when scrolling?

I just bought a brand new S2, I am using stock rom 4.04.
I noticed in the browser, apps, system etc...when scrolling, the text (but also any other graphic element on the screen) flickers a lot...
I get a really choppy scrolling in general...it looks like the screen is refreshed at a low frame rate...
I noticed this thing immediately, I use an HTC Desire S and an iPod Touch on daily basis and I do not have this problem.
Is my unit defective? Is it a stock rom issue? Has anyone got this problem?
Thanks
Edit: it is somehow better if I disable "Force GPU rendering" in the developer options
Do an update via.
And/or
Make a factory reset.
If anyway probs, u maybe can use ur guarantee?!
At least it's not normal.
CHEERS

[Q] Shadowgun deadzone bluriness on Asus padfone

Hello Guys!
Yesterday i updated my Asus padfone to JB 4.1.1 and kow the game has bluriness,I have tried screen filter and tried to get it work by disabling HW overlays and forcing GPU rendering.But nothing works for me.Disabling HW overlays removes bluriness,but then my screen brightness is so low that i cant even see who im shoting at.
Before update everything was perfect.Im so dissapointed in the JB 4.1.1.
Thank you.

[Q] Flickering Multicolored Lines

For the past week or so my phone has had flickering multicolored lines flash across the homescreen(s)/lockscreen when I turn the display back on. Sometimes it will also happen if I'm sitting on the homescreen with the display already on.
Here is my Rom history as the problem began:
Was on supernexus (Android 4.2.2 I believe) - issue was not present
Flashed Unofficial Slim build 6 (wiped cache/dalvik/factory reset before install)- started having the issue
Flashed Unofficial Slim build 6.2 (wiped cache/dalvik)- issue still present
Flashed AOCP 5.7 yesterday (wiped cache/dalvik/factory reset and formatted internal SD)- thought issue was gone, but it started happening again today.
I tried taking screenshots but the issue disappears as soon as I press the volume+power button to take the screenshot. This only seems to happen when I'm on the homescreen/lockscreen, I dont think it has happened while in any other apps.
I'm wondering if this might be an issue with the specific version of the Nova launcher, as I believe that is the common denominator between these Roms (isn't AOCPs launcher based on CM's nova?). I just installed go launcher and the problem seems to be gone (for now).
Has anyone else seen something like this? I apologize if this has been discussed somewhere, I spent several hours searching Google and XDA before posting. I can post a picture later when I have access to another camera phone.
Same issue here
I have the same issue at the lock screen. Prevalent on all JB roms I have tried, carbon, revolt & slim bean.
I'm currently using Carbon nightly. I have not seen a fix for this yet. I have heard it might be an issue with the processor waking up from sleep.
After installing Go Launcher Ex opening it a couple times and then going back to using the Aspire launcher that came with AOCP, I haven't had this issue again all afternoon. Didn't have it at all yesterday though, so it might come back.
I played around with all the brightness settings but it didn't seem to do anything. Do you happen to have any pictures of the effect you are getting? I'll try and post a picture of mine tonight if it happens again. Thanks!
About 3 hours ago, I changed some GPU & lock screen settings and the issue has not reappeared.
I will post back either later tonight or tomorrow morning with some info.
I haven't taken any photos of the problem yet. By the way, do you usually experience the issue on lock screen coming from a screen off state?
ditto on this. I have Cyanogenmod 10.1 installed and I get these lines intermittently.
Try turning off CRT animations and disable hw overlays.

Go to settings, developer options scroll half way down and you will find it. You will have to disable it every time you reboot or you can use two paid apps from the market. These apps are tasker and secure setting they are both worth every cent.

Do you have any backlight handling apps? I used lux all the time and it stopped after I disabled it.

Just enabled "Disabled HW overlay" and "Force GPU rendering". Like some of the users suggested, I found about the possible solution from this video:

(go to 1:40)
I usually get the flickering with the lock screen (I use WidgetLocker Lockscreen). I was having some flickering this morning and checking both of those options seemed to immediately cut out the flickering.
I ran across it(the flickering lines) on one of the 4.2.2 roms, can't remember exactly which one but what I ended up having to do was disable one of the tweak apps it came with and install Trickster Mod only. Worked for me, no more flickering or rebooting, not sure what the cause may have been but have had no other issues after that for I believe it was 2 weeks
Please elaborate

By chance can you give some more details about this Trickster Mod like where to find it and what it is supposed to do?
A link to a thread would be great

Scroll down to my post there. If you still need help, just let me know.
Trickster mod I believe is mainly for Rom's that have Kernels that can be OC'd or Under Clocked. Kind of the same as Android Tweaker or SetCPU but is a little smoother for me IMO.

[Q] Could something similar to this be used to rid us of slow wakes in AOSP ROMs?

So this is a bit of a pot shot but the I9300 is the 3rd device I have owned with the slow wake issue. On my previous device (huawei g300) i used this kernel mod after being told that vsync was partly to blame.
github.com/KonstaT/zte-kernel-msm7x27/commit/368448b773f6917c213f37f7dd1a882ba588b120
It worked a treat and was soon inclueded by our resident CM ROM dev at the time. My questions are:
Could we benefit from this or something similar on the i9300? Has the cause of the slow wake been identified?
Thanks
In Ultima Rom there is an option to fix this wake delay
And it is mentioned there that I9300 goes in deep sleep mode and thus a delay occurs in order to wake the cpu
when the Fix is applied then the delay is gone. I have personally not checked the fix because i am ok with it, but i can try and let you know but too lazy for that
Also so much on my plate going on.. but this i just shared with you is what i read.
