Green and white squares flickering on screen

Hi everyone,

In the last few days I have been working on a new project.
In the editor everything works perfectly,but when i created my first build green and white squares started flickering on some spots on the map.
They mostly appear when i move my character and very rarely when he is not moving.
So far I found atleast 5 spots on the map where this happens and I am unsure how to fix it or what might be causing the problem.


Here are some pictures:

 

Strange... go into your project quality settings and change your pixel light count and see if the squares appear any different. If they do, it's a problem with pixel lights (I don't know how to begin fixing it, but knowing the problem is a start).

You could also try pausing the game in-editor when you see one are check the scene view to make sure it's a graphic bug and not a stray GameObject

 

Well,the biggest problem is,it does not happen at all when i try to play it in Editor,it only happens after i create a build and try to play it without unity,and it takes me about an hour to render a build.I was kinda hoping that this was a common error caused by some stupid mistake i made in build settings.I remember ticking both static and dynamic batching,but rendering was already half way through so i could not change it.Could it be caused by that or something simillar?

 

It wouldn't be caused by batching. Batching takes the mesh information from several objects and fits them into shared buffers to greatly reduce GPU workload at the cost of a slightly increase CPU workload.

It looks to me like it's more of a bug with lighting or post-process effects. I wish I could help you more, but I haven't done much with post-process effects in unity. (did you try modifying the pixel light count?)

 

Hello!
Did you ever find the source for this issue? I have been experiencing something similar to this recently. I get the white or green flickering squares. However, I do get them in the editor as well.
Any solution?

 

Nope,sorry.
I abandoned the project long ago,since my problem existed only in builds,not in editor nor in play mode so i could not find exactly what what causing the problem without creating a new build each time.
Hope you find the solution,it might help someone else as well

 

hey just wanted to leave this here for anyone coming across it, i had this issue and for me at least it turned out to be hdr on the camera and bloom post processing conflicting with each other. I turned on the anti flicker under bloom and it seems to have fixed my issues. although i only had white squares not green.
