I’m getting weird lens flair effects all over the default example projects.
Here is what it looks like (C++ puzzle project without any modifications): – but it’s the same in other default project templates as well.
I’ve built from source code on Linux, repo branch 4.10. My NVidia driver version is 340.96 x86_64. The about dialog lists the version as “4.10.4-0+++depot+UE4-Relesaes+4.10”
