Render Incorrect with GPU GI Light Cache Fly-Through Mode

[omaryo]

When I set to GPU with GI in Light Cache Mode Fly-Through the image render always got darken on half top of image.
The scene just simple setup with sphere and Dome Light.

It appears that is indeed the case. Seems to be a core issue related to light linking so I can't say for certain how long this will take to fix.

I will ping you once I know more.

Thank you!
