So in order to report this as a bug, I am going to need a way to reproduce it in a new blank project. From looking at the video, it could be a number of issues like your GPU driver for the specific engine version or just a rendering setting.
Could you provide me with steps so I can get the flickering to occur on my end?
I will need the users full ‘dxdiag’ as well as any other information that might hint towards how you believe the flickering is occurring.
Here is the DxDiag. should also provide the driver version. We tested a blank packaged project and the shipped game on steam both ran on 4.14 without adjusting any settings. I asked the player to update his Drivers but that did not solve it, so i assume it should be related to the AMD GPU used.
If anyone more Information comes up i will post it here, but hopefully that dxdiag is enough to figure out a way to reproduce it.
As I mentioned, I would need a way to reproduce this issue on my end in order to begin to understand what could be occurring. As it stands, I have no way of getting this flickering to occur on my end. So it falls on the users to narrow down steps in order for us to address the situation.
