Since I upgraded to Unity 5.1, everytime I press a button, the UI flickers. This is on android.
The same build with Unity 5.0 doesn’t flicker. Now that I’ve upgraded my projects to 5.1, I can’t go back. I’m close to a deadline and can’t afford the UI to flicker everytime a button is pressed.
Any suggestions on how to fix this?
I’ve think I have the same issue, since upgrading to 5.1 I get strange flickers when a button is pressed. Only thing I do is switch panels off and on. Any help would be much appreciated.
BTW my bug report got ignored. 
I understand that Unity Technologies is not required to help us since they were nice enough to offer a personal version of it, but I thought that it takes its bug reports seriously.
I am having this issue as well. I’ve had it since upgrading to 5.1, it’s only on some devices (Samsung galaxy tab lite 3, android v4.2.2)
These threads may be related (I’ve posted in some of these too)
however, none of these have helped me. I have already upgraded to latest patched version 5.1.1p2
Attached is a gif I posted in one of the threads showing the flickering. This also happens sometimes when I press InputFields too. Often after the first flicker, it won’t happen again until the object is setactive(false) and then setactive(true).
If this thread gets no traction I will start a new thread with a lot of information and hopefully it won’t get ignored. This is causing me a lot of headaches as I now need to build some devices with 5.1 and some with 5.0 for releases.
Is there a bug# for this?
I haven’t submitted one yet, but perhaps Wolfdog can share the # of theirs?
If not, I can submit one and try and get a reproducible project to zip up and attach if that will help move things along?
I went ahead and made a test project anyway (attached). I deleted the Library folder as this made the zip too large; this should rebuild when you open the project.
This project was built with Unity 5.1.1p2 on a Windows7 machine, although I’ve had this bug in all 5.1.x versions I have used. The flickering occurs on a Samsung Galaxy Tab 3 lite, running Android 4.2.2. It does not seem to happen on Windows or the editor - possible it flickers too quick to see? I have already tried tweaking various settings to no avail. The flickering does not occur in 5.0.
I tried to make a gif again but the movie file was too long so here is an avi file hosted on my website:

If this does turn out to be a bug and you find an intermediary workaround I would love to know about it!
If you need any further information, please don’t hesitate to ask.
That is exacly what happens to me. Because of this, I’m still with 5.0.2. 
I’m on Samsng Galaxy s3 Mini. Perhaps a Samsung problem?
i have a galaxy note2 and a cello budget tablet i will test on tomorrow when i am back in the office. My gut feeling is it affects a small number of tablets on certain builds.
It doesn’t happen on my Samsung Galaxy Note 2, running android 4.3. The other tablet I have has been swiped by someone else, but I’m sure I tested it with the initial version of 5.1 and there was no flickering, I will try and find out what version of Android that is running on from a colleague.
Wolfdog, what version of android are you running on your s3 mini? Do yo have a bug number that I can view and possibly add some information to? I’m thinking of the test project above etc
Edit: She got back to me quicker than I thought, Cello tablet running 4.4.2. Maybe I will try and find someone in the office with 4.2.x to see if it flickers for them as well!
I’m on Android vecrion 4.2.2. I just got a reply about the bug report (1 month after submitting it) saying that the problem couldn’t be reproduced. I will try to submit another one with more info (as that’s what was asked of me in the reply).
You could point them here to my test project as it reproduces the bug.
It’s no coincidence you are on the same android version number and we have the same issue! It could be an android bug?
Perhaps it became outdated?
it’s probably an anomaly with that android version. I’m honestly not sure what to do as I can’t upgrade this tablet, withotu a fix I will be stick on 5.0.x.
Could you possibly send me the bug# when you submit it please?
sure, I will probably do it sometime today.
I just submitted another report.
Case 709632
I can’t find your bug in the tracker, does it get manually added by someone after you submit it? Thanks for submitting it.
I noticed Unity 5.1.1p3 has been released as of Friday, I’m installing that now on the off chance it fixes this issue; the patch notes do not make me hopeful though!
EDIT: Still an issue in 5.1.1p3.
Wolfdog, would you be able to link me to the bug somehow so I can keep an eye on it? I can’t find your case in the issue tracker.
It would be nice to know somehow if this bug has or has not been officially acknowledged by the Unity UI team and be able to track any progress on it without needing to harass you for updates =)
This issue is quite a pain for me as mentioned in previous posts.
Same. This is the url from the thingy: http://fogbugz.unity3d.com/default.asp?709632_184le49agup9nqk2
I don’t know how useful it is or if it will even show up when someone else goes there, but anyway. Let me know if the link works for you or if it ask to login or something.
Thanks for that, I can see the page =)
If it helps my Kernel version was 3.4.5-2751957 and baseband (build number?) JDQ39.T110XXUANI7. Perhaps adding this to the issue might help? I am using a Samsung Galaxy Tab Lite 3 (SM-T110) - more information can’t hurt I’m sure!
