Light with disk or cylinder shape not showing up in GPU render?

[GabrielChiang]

Hey guys, seems that a light with a disk or cylinder shape is not working on GPU rendering. I have a quad area light and a disk light in the scene. The moment I switch it from disk to quad, it works (as a quad only). Am I doing something wrong?

Thank you for reporting. This is a known limitation.

For a work around, you can add a roundness value of 1 to a quad light to simulate a disk light and add a mesh light to a cylinder object.
