[Q] OpenGL Problems with Evila_Alex V 1.0 - Acer Iconia A500

I installed Evil_Alex_Unleashed ver 1.0 on my 501 and it mostly works great. I do however have problems with OpenGL:
Some Games freeze (Ritide GP, Beach Buggy)
Some Games just crash (Clouds & Sheep, Google Maps)
Rebooting the tablet often fixes the problem, but only for a limited time.
I can PM a logcat of such a crash, but don't want to post it (may contain other information).
The developers of Clouds & Sheep reckon that in their case OpenGL is crashing, potentially due to a driver problem. Can't say with certainty whether the other apps also crash because of OpenGL or due to some other problem, but it does seem likely. I did not have those problems with HC.
Does anybody else have those problems (Evil_Alex or stock ICS)? Is there a fix?

This is a well known problem. AFAIK it is caused by a memory leak in OpenGLES in graphic driver for ICS/JB. This also breaks Chrome browser after some time.

Thanks. Some follow-up questions:
Is this a problem specific to Evil_Alex, the Iconia 501, or any ICS/JB device?
Where can I find more info on this problem?
Is there a work-around or fix for the problem (e.g. give the driver more memory, use a different driver, ...)?
Does this problem affect everybody, or just some tablets?
Cheers,
Carsten

@ich23: I'm not sure but it seems it affects at least all ICS/JB based firmwares for Tegra2 based Acer tablets. I don't know if other Tegra2 devices are affected too as I don't follow threads on forums for those devices.

Apps not responding as expected.

I was wondering if anyone has experienced problems with some of the following apps after updating to Taboonay 3.0.1 or any other ICS ROM. The issues I am experiencing are as follows...
Netflix - TV shows - I can not scroll through the list to find the episode I want to watch. It is as if the touch is disabled for the window that pops up. I can watch movies without incident as you do not have to select a specific episode.
Stupid Zombies - I can aim, but I can not fire. Once I release the screen, nothing happens.
Beavers Revenge - I can not fling anything. I can zoom, but when I want to launch a critter, I can not move the tail.
I have heard back from one DEV group, and they informed me that the their program is ICS Compatible. Is this just a pre-release issue that I am seeing then? Other than these 3 issues, I love the experience of ICS and the Taboonay Rom. Thanks to all who have made Taboonay 3 possible.
I too have several games that are unplayable on Flexreaper's ICS release. All are touch screen issues. May be a driver issue that will be fixed with the official release. I just uninstalled the offending apps.
The roms you both are talking about are from a Leak .Both developers state there will Issues and Compatibility problems .Also some app developers do not always have the time or ability to check there apps against all roms. Most apps are tested and debugged against the so called well written api pushed from google.. Meaning yes issues . It will likely be hit and miss until there is a so called Complete bug free rom/ kernel. for ics on our tablets..
Hope this helps explain why these issues happen .Hang in there it will continue to get better. Or go back to honeycomb. .
Good Luck

[Q] Blue textures in some games - problem

I noticed, that in few games I have blue textures. Of course its unplayable.
- stock rom 4.3
- kernel flamingomonkey 3.4.39
Could be kernel issue?
Or an incompatibility issue in the app that needs to be sorted out due to a new GPU driver as well as a new graphics rendering system that 4.3 uses. OpenGL was upgraded to a new version and maybe some of the system calls those games use are not compatible with the new version.

What games? I most likely own some of them. I have also used flamingmonkey so can confirm whether it is a driver issue or not. Personally I haven't had this issue, and I have tried quite a few games. This can indicate faulty hardware on PC GPU's so you definitely want to get to the bottom of this ASAP.

[Q] S4 - Webkit problems

I am developing on Android with cross-platform coding which uses the webkit feature for printing out the GUI.
I have noticed that my app compiles and looks good on several android phones but on the S4 there are serious webkit issues. No errors are thrown but the canvas objects are not being displayed properly and the problems seem to be completely random. The same code will display different types of rendering problems during each refresh.
I have searched the net and it appears to be a specific problem for the S4.
Are there any known solutions to this problem? Or are any webkit based apps pretty much useless on the S4? Specifically I am developing using Phonegap and debugging using Eclipse - testing is being done on an actual device, not virtual.
I have had some minor success by turning off hardware acceleration but the rendering problems are still so bad that the app would not be useable on the S4.
Thanks.

[BUG Report] GT-I9100 Dialer isnt correctly working / AOSP Camera Bug

Hey,
I didnt know where i should Post my Bug Report so if its the wrong section dont hold back to tell me.
I'm currently using my Galaxy S2 for daily use and after flashing some Kitkat Roms Omni is in my opinion the most stable rom and with Nova + ART a damn fast Rom, so thank you very much for supporting my Device.
I dont know whats happening the last weeks but it all began with an Opendelta Issue, i wiped all Data / Factory Reset via TWRP and flashed the Rom completely new and OpenDelta still didnt work, it just said every day its all up2date. Now after a couple of days it is working again, dont know if it was a Server Issue or something else - at the official Omni Page no one post News so i have always to guess whats happening
Currently i found 2 Bugs, if you want to call someone you open up the Dialer and then the Button for the Numbers but after clicking it, theres nothing(Screenshot is attached). You have to go back and try it again then the Numbers are there. The second Problem is that there is no Zoom in the AOSP Camera App if you record a Video. My currently workaround is the Google Camera App, there all is working fine. Also there are some Issues with Apollo , freezing , doesnt update the Song DB etc. , dont know why its so popular - its horrible. Replaced it also with a 3rd party App - Omich/Rocket Player.
The last Problem is that not everywhere in the Settings the correct language is used, if you need some translation help im sure many users would like to help(including me) but that is in my opinion nothing critical .
...and sorry if my Text was hard to read, its not my native language but im working on it :silly:
Regards
Per the FAQ, this is not the place to put bug reports.
However, I9100 hasn't been maintained in a long time, so filing a bug report will be a waste of time. Support for this device is currently going to be dropped with Android 5.0, and if it receives 4.4 bugfixes, that'll have to come from a new maintainer as none of the former maintainers have time/motivation for the Exynos 4210 devices these days.
Some of the issues you describe with Apollo aren't Apollo issues, but the result of a very deep-down core bug that has a side effect of screwing up storage access. This bug has been known for nearly a year (there's a big thread disucssing it somewhere around here...) and still no one has found a fix for the root cause. In fact, it's one of the #1 reasons the device is getting dropped for L. (It will absolutely not receive nightlies unless someone finds and corrects the root cause.)
Hey,
Thank you for your response. :good:
I reported the Bug on jira and there is a workaround for the Dialer Bug: Setting The Animator Scale higher than 0.
The Drivers are the problem right?

Well, there are three things you listed:
1) Dialer stuff - probably some sort of odd HDPI issue and/or graphics subsystem stuff. The Exynos4 graphics subsystem is why many developers don't want to ever touch the platform again.
2) Zoom in video - What resolution was Google Camera? Zoom has NEVER been available for 1080p resolutions on the Exynos 4210 family, not even stock firmware will zoom in 1080p
3) The storage issues are a symptom of a deep-down kernel bug that no one has found the root cause of. This is the #1 reason the device is getting dropped for 5.0 - there is no chance even if a new maintainer steps up that nightlies will resume until someone tracks down the root cause of this one. http://forum.xda-developers.com/showthread.php?t=2612329 has more discussion (warning: It's long...)

Switch back to old GPU drivers?

Hi there,
I'm having issues with the new r12p1 graphics drivers when using Dolphin emulator (https://forums.dolphin-emu.org/Forum-android) where performance is bad and there are a lot of graphics issues, in fact the issues appear very similar to those experienced with the galaxy s6 on Marshamellow rom.
So I'd like to keep the old GPU drivers so I can use the Dolphin emulator but use the newer roms and kernels which are including the new GPU driver - does anyone know of a way to do that??
Thanks in advance.
If you want to use old driver...
-Use older rom and kernel.
-(Might not work) Use newer rom and replace some libs file with older one(I don't know which one) with old kernel.
These are 2 option I can come up with.
Also
Have you tried reinstall the app(uninstall and install again)?
Some apps that experience graphic glitch after update can be fixed by reinstalling apps.

Thanks for the ideas, I tried reinstalling the app but no joy, I think the driver is just buggy.
I'm going to try backing up the old drivers and importing them to the new rom and also installing a new kernel without the new drivers.
Hi, I used dolphin emulator in my Samsung Galaxy S6 Edge for playing Dragon ball zee bt3 and it was extremely slow thus I tried to run the game in vulkan support and after that the game was fine but the video doesn't appear and it only shows a black screen while sound keeps coming from the background, so anyone have any idea in how to fix this vulkan support glitch. I have Naugat 7.0 and 3GB Ram with 32GB Rom......pls help me as I had seen many people play this game on small phones like Motorola G4 etc..
