Game flickers when updating SceneCapture2D

When I update a SceneCapture2D using the “Update Content” node game flickers.

strange thing is, I can’t reproduce this in a new project. I get flickering in multiple independent projects, but I can’t get it in a new project, even after setting everything up exact same way as in another project where flickering occurs.

So I chose smallest project where I can get bug to show up, removed all unnessessary stuff and here you can download it:


Really just a small project with like nothing in it. It just flickers. flickering does only occur in standalone, not in PIE.

If you find reason for flickering, please tell me what it is. It’s making me crazy. For hours now I try to get it to flicker in a new project, it just does not work. I seem to miss something. But setup is so simple, just a SceneCapture2D actor which updates itself once a second with a timer. I am not even using a custom game mode. Just default flying camera. Btw, if you try to change gamemode in project settings project will crash, so there is another bug.

Hi John,

Could you open a new post for crash you got from changing GameMode in Project Settings, and include log after crash occurs? I believe it may be related to another crash found in 4.8.1 that has already been fixed internally, but I’d like to confirm. Thanks! I have someone looking into flickering for you.

Thanks! crash with GameMode is not important, I could just fix it with manually writing a correct location in ini file I guess…

Hi John -

Yep, I am not certain what exactly is causing it but there does appear to be a jump in post process settings when you have Scene Capture 2D running on update Content node in standalone Game. I have reported bug as UE-17989 and will keep you informed as we investigate a solution.

Thank You

Hi Eric, could you give me any update on this? It’s still in 4.9.2.

UE-17989, as of October 16th 2015, is backlogged. I have bumped community interest up for you.

Hi Eric, any new update on this?

Unfortunately no new news, status remains same.

Hi Eric, any update on this now or still same?

Hi -

I have same issue on 4.11.1 git hub version.
I create actor with screencapture2d for inventory item preview (used in UMG widget) and set up it similar to this tutorial:

While playing in editor everything looks fine, but in packaged game all screen starts to flicker when screencapture2d updates. Currently i set it to not update every frame so flickering occure only one time. Any ideas how to fix it?


We are impacted by this bug too. Is there still no news?
