Hello, I have been dealing with this problem for whole week.
Every time I build one specific project and run the .exe all I get is white / black flickering all around the screen. The project works perfectly fine in edit mode or in game mode inside the software. But every time I build it it starts crazy flickering.
I did a little test. I moved my whole model to new Scene and for first whole day it was working fine. But after I run it to high quality light bake. I came back to the same problem.
Have you tried building for x86_64 instead of x86 already?
I think I had a similar problem when running scenes with lots of objects and big textures in the past.
You might be over the 4gb limit of 32bit builds.
